Two SIC slots can form one DSIC slot. MSR and MSR can implement voice data processing without any VCPM card. If you need voice support, insert a VPM card into the VPM slot on the main control board, and then install a SIC-1VE1 or SIC-1VT1 on the router. Only MSR and can support SIC-1VE1 and SIC-1VT1. MSR 20-12, MSR 20-13, and MSR all include two sub-models. One sub-model supports WLAN and the other does not. You can purchase the appropriate sub-model as required. The Boot ROM stores the Bootstrap for booting the router. The memory stores the communication data between the system and the CPU during the system operation. The flash memory stores the BootWare, the software system and the configuration file of the router. Do not unplug the USB device during USB data transmission; otherwise, data loss or even hardware failures may occur. The wireless module can not be purchased separately. By default, the impedance of the fixed E1 interface on MSR is 75-ohm. Using the internal DIP switches, users can change the interface impedance from 75-ohm to 120-ohm. For detail information, refer to Chapter 6 Hardware Maintenance. 2

For detailed information about interface cards, refer to MSR Series Routers Interface Module Manual. For the types of interface modules that each model of the MSR 20-1X routers can accommodate, refer to Appendix A Interface Card and Interface Module Purchase Guide in the MSR Series Routers Interface Module Manual. 11

19 SICs and DSICs MSR 20-1X routers adopt modular design and provide the following interfaces to support a wide range of optional SICs/DSICs: Synchronous/asynchronous serial interface Ethernet port E1/T1 interface ISDN BRI/PRI ADSL interface Voice interface Layer 2 Ethernet interface 12

20 Installation Preparations Requirements on Environment MSR 20-1X routers are designed for indoor application. To ensure the normal operation and prolong their service life, the installation site must meet the requirements mentioned in the following sections. Requirements on Temperature and Humidity To ensure the normal operation and prolong their service life, the temperature and humidity in the equipment room shall maintain at a certain level. A long-term high relative humidity will quite likely result in poor insulation performance, electric leakage, mechanical property change, and corrosion, while a low relative humidity will result in looseness of fastening screws owing to shrinkage of insulation washers, or electrostatic discharge (ESD), which may damage the CMOS circuit on the router. A high temperature will speed up the aging of insulation materials, and thus will greatly lower the reliability of the router and shorten the service life. Table 12 lists the requirements on the temperature and humidity for MSR 20-1X routers. Table 12 Temperature and humidity requirements in the equipment room Temperature Relative Humidity 0 C to 40 C (32 F to 104 F) 5% to 90% (noncondensing) Requirements on Cleanness Dust is harmful to the safe operation of the router. Dust on the chassis may result in static absorption, causing poor contact between metal connectors or joints, which may not only shorten the service life of the router, but also bring about communication failures. Especially under the condition of a low indoor humidity, dust is easier to be absorbed. Table 13 lists the requirements on the dust concentration and diameters in the equipment room. Table 13 Limitation on dust concentration and diameters in the equipment room Diameter (μm) Concentration (particle/m³) Besides, the contents of salt, acid, and sulfide in equipment room shall be strictly restricted. Harmful gases will accelerate the corrosion of metal parts and the aging of some parts. Table 14 lists the concentration limit of SO 2, H 2 S, NH 3 and CI 2 in the equipment room. Table 14 Concentration limit of some harmful gases in equipment room Gas Concentration limit (mg/m 3 ) SO H 2 S

21 Gas Concentration limit (mg/m 3 ) NH Cl Requirements on Electrostatic Discharge Prevention Although many antistatic considerations have been given to MSR 20-1X routers, damage to circuits or even the routers may still happen when the amount of static charges exceeds a certain limit. In the communication network to which the routers are connected, static induction mainly comes from two aspects: the external electric field (such as outdoor high voltage power line or thunder) and the internal system (such as indoor environment, floor materials or the router equipment structure. Thus, the following should be considered to safeguard the equipment against ESD. Make sure that the router and the floor are well grounded. The equipment room is dust-proof. Maintain an appropriate humidity and temperature. Wear an ESD-preventive wrist strap and uniform when contacting a circuit board. Place the removed circuit board on an antistatic workbench, with its face upwards, or put it into an antistatic bag. When observing or moving the removed circuit board, it is only allowed to touch the edge of circuit boards, instead of elements on the circuit board. Requirements on Electromagnetic Environment The interference sources, no matter where they come from, affect the routers in the form of capacitance coupling, inductance coupling, radiation of electromagnetic wave, and common impedance (including the grounding system) coupling. Therefore, the following should be considered: Take effective measures to prevent the power system from being interfered by the power grid system. Separate the return terminal of the router from the grounding device or lightning protection grounding device of the power supply equipment and keep them as far as possible. Keep the router far away from radio stations, radar, and high-frequency devices working in high current. Use electromagnetic shielding when necessary. Requirements on Lightning Protection Although many measures have been taken to protect MSR 20-1X routers from lightning, if the lightning intensity exceeds a certain range, damage to the router may still happen. To protect the router from lightning better, the following should be considered: Ensure the PGND wire of the chassis is well grounded. Ensure the grounding point of the AC power socket is well grounded. Install a lightning arrester at the input end of the power supply to enhance the lightning protection capability of the power supply. Install a special lightning arrester at the input end of outdoor signal lines (for example, ISDN line, telephone line, and E1/T1 line) to enhance the lightning protection capability. 14

22 Checking the Rack When installing MSR 20-1X routers, make sure that: There is spacing reserved at the air inlet and exhaust in the router for the purpose of heat dissipation of the router chassis. The rack has a good ventilation system for heat dissipation. The rack is solid enough to support the weight of the device and the installation accessories. The rack is well-grounded. Safety Precautions Routers play an important role in data communications network. Please pay attention to the following signs: WARNING: Means the reader be extremely careful. Improper operation may cause bodily injury. CAUTION: Means the reader be careful. Improper operation may cause data loss or damage to equipment. When installing or working on the router, observe the following recommendations: Keep the router far away from heat sources and dampness. Ground the router correctly. Wear an ESD-preventive wrist strap, making sure that the strap has good skin contact. Do not insert or remove interface modules or interface cards of the router when the power supply is connected. Do not insert or remove a cable when the power supply is connected. Connect the interface cables correctly for the router. Do not connect a telephone line (including ISDN line) to a serial port. Use laser with caution. Do not directly stare into apertures or fiber-optic connectors that emit laser radiation. Equip an uninterrupted power supply (UPS).

24 Installation Installation Flowchart Figure 11 Installation flow for MSR 20-1X router Installing the Cabinet MSR 20-1X routers can be installed into an N68 cabinet. For the cabinet installation, refer to the part discussing cabinet installation. Skip this section if you do not install the router in a cabinet or use the cabinet of another vendor. Installing the Router Install the router after you have completed the installation preparations. The router can be installed: On a workbench 17

25 In a cabinet On a wall Installing the Router on a Workbench In case that no 19-inch standard cabinet is available, you can put the router on a clean workbench. When installing the router on a workbench, Make sure that the workbench is stable and well grounded. Reserve a space of 10 cm (3.9 in.) around the router for heat dissipation. Do not place heavy objects on the router. Installing the Router on a Cabinet Dimensions With mounting brackets, you can also install MSR 20-1X routers in a 19-inch standard cabinet. The dimensions of MSR 20-1X routers without feet and mounting bracket are mm ( in.). Installation procedure Step1 Check that the cabinet is stable and properly grounded. Attach two mounting brackets to the front or rear panel of the router with screws. Step2 Put the router in a tray. Depending on the actual situation, slide the router along the guide rails to an appropriate position, keeping a proper distance between the router and guide rails. Step3 Fix the router horizontally by fastening the mounting brackets to the cabinet with appropriate pan head screws. The specifications of pan head screws should satisfy the installation requirements and rustproof treatment has been made to their surfaces. Figure 12 Install an MSR 20-1X router in a cabinet (1) Mounting brackets 18

26 Installing the Router on a Wall In addition, you can install MSR 20-1X routers on a cement wall or wood wall. Figure 13 and Figure 14 show the recommended sizes (in mm) of the screw and anchor for wall-mounting. Figure 13 Screw sizes Figure 14 Anchor sizes A 21.8 B C 3.7 The wall-mounting procedure is as follows (see Figure 15): Step1 Drill two holes in the wall, with the two holes on the same horizontal line and a distance of 170 mm (6.69 in.) between them. Step2 Insert an anchor into each hole. Step3 Drive the screws into the anchors, keeping the screws at least 1.5 mm (0.06 in.) outside the wall. 19

27 Figure 15 Wall-mounting 170 mm Step4 Align the installation holes at the bottom of the router with two screws and hang the router on the screws. CAUTION: When mounting the router, keep the network interface facing downwards and the two sides with ventilation holes vertical to the ground. Installing Generic Modules For the procedure for installing generic modules, including various smart interface cards (SICs), refer to MSR Series Routers Interface Module Manual. Connecting the PGND Cable WARNING! Correctly connecting the protection grounding (PGND) cable is crucial to the lightning protection and electromagnetic susceptibility (EMS) of your router. You must correctly connect the PGND cable when installing or using the router. The power input end of the router is equipped with a noise filter. The neutral ground of the power input end is directly connected to the chassis and called PGND (also known as chassis ground). The PGND must be well grounded so that induced current and leakage current can be safely led to the ground and the EMS of the router can be reduced. The PGND cable can also protect the router against high lightning voltage resulting from external network lines such as E1/T1 line or ISDN/PSTN line. The protection grounding terminal marked with a grounding label is located on the rear panel of the chassis, as shown in the following figure: 20

28 Figure 16 Protection grounding terminal of the router Use a PGND cable to connect the protection grounding terminal to the ground, with the grounding resistance not greater than 5 ohms. Likewise, if the router is installed in a 19-inch standard cabinet, the cabinet shall also be well grounded. WARNING! The router in operation must be well grounded. Otherwise, the router cannot be protected against lightning, and consequently, the router or even the peer device may be damaged. Connecting the Power Cord MSR 20-1X routers support AC power input only. Power Socket and PGND Table 15 Power socket and PGND of MSR 20-1X routers Item Power socket PGND Description Connected to a 100 VAC to 240 VAC power Connected to the ground with a PGND cable Connecting the AC Power Cord AC power supply Rated voltage range: 100 VAC to 240 VAC, 50 Hz to 60 Hz The figure below shows the appearance of the power socket on the router: Figure 17 Appearance of the AC power socket on the router (1) Power switch (2) AC power socket 21

29 Recommended AC power connector A three-terminal, single-phase power connector with a grounding contact is recommended. Normally, the grounding contact of the power supply system in a building was buried during construction and cabling. Before connecting the AC power cord, you must make sure that the power supply of the building has been well grounded. Connecting the AC power cord Step1 Make sure that the PGND is securely connected to the ground. Step2 Move the power switch of the router to the OFF position, and connect one end of the power cord shipped with the router to the power socket on the rear panel, and the other end to an AC power source. Step3 Move the power switch to the ON position. Step4 Check whether the power LED on the front panel of the router is ON. If the power LED is ON, the power cord is properly connected. Installing Antennas Fasten the attached antennas onto the router. Avoid over-tightening. Once the network is up and running, you may need to adjust the antennas to achieve better coverage. Usually, the antennas should be vertical to the ground or ceiling to achieve the optimal coverage, as shown in the following figure. Figure 18 Installation of router antenna CAUTION: Do not touch the antenna top, especially after the antenna is connected with the grounding contact. Otherwise electrostatic discharge (ESD) may damage the router. Connecting the Console Terminal Console interface MSR 20-1X routers each provide an RS232 asynchronous serial console (CON) interface for router configuration. Table 16 describes the attributes of the console interface. Table 16 Attributes of the console interface Item Connector type Interface standard Description RJ45 RS232 22

The following figure illustrates the console cable. Figure 19 Console cable Connecting the console cable Follow these steps to connect a terminal device to your router: Step1 Select a console terminal. The console terminal can be a standard ASCII terminal with an RS232 serial interface or a PC. A PC is more commonly used. Step2 Connect the console cable. Power down the router and the console terminal, and connect the RS232 serial interface of the console terminal to the console interface of the router with the console cable. After the console terminal and the router are powered on, the startup information of the router will be displayed on the console terminal if the connection is normal. Fixed Interfaces Layer 3 Ethernet Interface Interface attributes MSR 20-1X routers each provide fixed 100Base-TX Layer 3 Ethernet interface(s) and SIC slots for expansion. For detailed expansion rules, refer to Appendix A in MSR Series Routers Interface Module Manual. The following table describes the attributes of Layer 3 Ethernet interfaces. 23

Electrical Ethernet interfaces usually use category-5 twisted pair cables to connect Ethernet networks, as shown in the following figure: Figure 20 Ethernet cable Ethernet cables fall into the following two categories: Standard cable, also called straight-through cable. At both ends of a standard cable, wires are crimped in the RJ-45 connectors in the same sequence. A straight-through cable is used to connect a terminal device (for example, a PC or router) to a hub or LAN Switch. The cables delivered with the router are standard cables. Crossover cable. At both ends of a crossover cable, wires are crimped in the RJ-45 connectors in different sequences. A crossover cable is used to connect a terminal device (for example, PC or router) to another terminal device. You can make crossover cables by yourself. NOTE: In making network cables, shielded cables are preferred for the electromagnetic compatibility sake. Connecting the Ethernet cable Follow these steps to connect an Ethernet cable: Step1 Connect one end of the Ethernet cable to an Ethernet interface on the router and the other end to the peer device. For a 10/100 Mbps Ethernet interface that supports MDI/MDIX autosensing, you can use a straight-through cable or crossover cable to connect the interface to a hub or LAN Switch. Step2 View the LINK LED of the Ethernet interface after power-on. If the LINK LED is ON, a link is present. If the LINK LED is OFF, no link is present. In the latter case, check the line. 24

33 Step2 View the LINK LED of the Ethernet interface. If the LINK LED is ON, a link is present. If the LINK LED is OFF, no link is present. In the latter case, check the line. Connecting the AUX Interface to a Modem AUX interface AUX cable The AUX interface is an RS232 asynchronous serial interface, which can serve as a backup interface of a WAN interface and provide dial connection. In case of console failure, the AUX interface can function as the console interface. The AUX cable is an 8-core shielded cable. An RJ45 connector is equipped at one end and is connected to the AUX interface. A DB25 male connector and a DB9 male connector are equipped at the other end and one of them is connected to the serial interface of the Modem. Figure 22 AUX cable Connecting the AUX cable Follow these steps to connect the AUX cable. Step1 Plug the RJ-45 connector of the cable into the AUX interface on the main control board. Step2 Plug the DB-25 or DB-9 connector into the serial interface on the analog Modem. When using the AUX interface for remote configuration or dial backup, you need to connect the local Modem to the remote Modem over PSTN and then to the remote device. For the configuration procedure, refer to MSR Series Routers Configuration Guide. MSR 20-1X routers provide various interface cards and interface modules. For detailed information, refer to MSR Series Routers Interface Module Manual. 26

35 Removing the Slide Rails Figure 26 Loosen screws Figure 27 Draw out the slide rails Installing the Security Lock There is a security slot on the side panel of the router and the security slot is near the front panel. Through the security slot, you can use a security lock to lock the device to a bracket of the cabinet or an irremovable object to prevent theft. Verifying Installation During router installation, you must verify installation each time you power on the router, making sure that: There is enough space around the router for heat dissipation and the workbench is stable enough. The power outlet voltage is compliant with the voltage indicated on the label of the router. The PGND cable of the router is correctly connected. The router is correctly connected to the console terminal and other devices. CAUTION: The check after installation is very important. The stability, grounding of the router and power supply will directly affect the operation of the router. 28

36 Startup and Configuration Startup Configure MSR 20-1X routers only through the console interface for the first time. Setting Up the Configuration Environment Connecting the router to a console terminal To set up a local configuration environment, you need to connect the RJ-45 connector of the console cable to the console interface on the router, and the DB-9 connector to the serial interface of a PC, as shown in the following figure. Figure 28 Local configuration through the console interface Devece Console cable PC Setting the parameters for the console terminal Step1 Open the console terminal and set up a new connection. Select the serial interface to be connected in the Connect using field in the Connect to box as shown in the following figure. Note that the serial interface should be the one connected to the console cable. 29

37 Figure 29 Set the connection port in the local configuration Step2 Set terminal parameters. As shown in the following figure, in the COM1 Properties dialog box of the serial interface, set bits per second to 9600, data bits to 8, parity to none, stop bits to 1, and flow control to none. Then, click OK to return to the HyperTerminal window. Figure 30 Set serial port parameters Step3 Set HyperTerminal properties. Select File->Properties->Settings from the HyperTerminal window to enter the properties setting window as shown in the following figure. Set the terminal emulation type to VT100 or auto detect, and click OK to return to the HyperTerminal window. 30

38 Figure 31 Set the terminal type Powering on the Router Checking before powering on the router Before power-on, check that: The power cord and PGND cable are correctly connected. The voltage of the power supply is the one indicated on the label of the router. The console cable is properly connected, the console terminal has been started, and the configuration parameters have been set. WARNING! Before power-on, you must be aware of where the power switch is located so that you can disconnect the power supply in time in case of an accident. Powering on the router Step1 Turn on the site power. Step2 Turn on the power switch on the router. Checking/operating after power-on After powering on the router, check that: 1. The LEDs on the front panel are normal. 2. The console terminal display is normal. For the local configuration, after you power on the router, you can see the startup banner (refer to section Startup Process on page 32). 31

39 3. After the power-on self-test (POST), the system prompts you to press Enter. When a command line prompt appears, you can proceed to configure the router. Startup Process After power-on or during the reboot process, the following information is displayed on the terminal: System application is starting...

You need to restart the router if you want to enter the extended Boot ROM menu after the decompression process. Starting to get the main application file--flash:/main.bin! The main application file is self-decompressing Press Enter. The router enters user view and you can configure the router. Configuration Fundamentals In general, the router configuration steps are as follows: 32

40 Step1 Before configuration, you should make specific network requirements, including the objective, role of the router in the network, division of subnets, WAN type and transmission medium, network security policy and reliability. Step2 Based on the above requirements, draw a clear, complete network diagram. Step3 Configure the WAN interface of the router. First, configure the operating parameters (for example, the operating mode of the serial interface, baud rate and synchronous clock) of the interface according to the transmission medium of the WAN. For a dialer interface, you also need to configure DCC parameters. Then, configure the link layer protocol encapsulated on the interface and corresponding operating parameters. Step4 Configure the IP addresses or IPX network numbers of all the interfaces on the router according to the division of the subnets. Step5 Configure the routes. If it is necessary to enable a dynamic routing protocol, you should configure related operating parameters of the protocol. Step6 If special security is required, perform the special security configuration for the router. Step7 If special reliability is required, perform the special reliability configuration for the router. For the configuration details of the protocols or functions of the router, refer to MSR Series Routers Configuration Guide. Command Line Interface Functions of the command line interface The command line interface (CLI) of MSR 20-1X routers provide a number of configuration commands, which can be used to configure and manage the router. The CLI provides the following functions: Allows you to perform the local configuration through the console interface. Allows you to perform the local or remote configuration and directly log in to other routers for the management purpose by using the telnet command. Provides online help after you enter?. Provides network diagnostic tools, such as Tracert and Ping, to quickly diagnose the availability of the network. Provides all kinds of detailed debugging information to help diagnose network faults. Provides a command line interpreter, which adopts fuzzy search for the keywords of the command. If you enter a conflict-free keyword for a command, the command will be interpreted accordingly. For example, for a display command, you can just enter dis and the command will be interpreted. Command line interface view The command line interface of MSR 20-1X routers provide plenty of configuration commands. All the commands are grouped in system view. Each group corresponds to a view. You can use commands to switch between different configuration views. In general, only certain commands can be executed in a particular view. But some common commands (such as ping and display current-configuration) can be executed in any view. 33

41 Slot Arrangement and Rules for Numbering Interfaces Slot arrangement The MSR 20-1X routers provide many types of interfaces, such as console, AUX, Ethernet, serial interface (synchronous/asynchronous), and asynchronous interface. The following describes how these interfaces are numbered. Rules for numbering interfaces The interfaces of the MSR 20-1X routers are numbered with two dimensions : The interfaces are represented by interface-type X/Y, where interface-type can be serial, asynchronous, or Ethernet, X specifies the slot number and Y specifies the interface number. Fixed interfaces are on Slot 0 and the expansion slot is defined as Slot 1. Different interfaces on an interface module share the same slot number X. For each interface, Y starts from 0 indicates the interface sequence on the interface module, from left to right. If you install an SIC-4FSW in slot 1 on the MSR 20-11, the Ethernet interfaces are numbered as follows: Layer 3 Ethernet interface is numbered Ethernet 0/0; The Layer 3 Ethernet interfaces on the SIC-4FSW module are numbered Ethernet 1/0, Ethernet 1/1, Ethernet 1/2, and Ethernet 1/3. 34

42 Software Maintenance Introduction Files Managed by the Router BootWare file Application files The BootWare file is used to boot an application. A complete BootWare file includes two segments: basic and extended. By default, the MSR 20-1X routers define three application files for booting: main, backup, and secure. The system selects these three files in sequence to start up the router. Currently only one application file is stored in the Flash memory of the MSR 20-1X routers due to limited memory size. To change the file selection sequence or modify an application file, refer to Maintaining Application and Configuration Files on page 55 for details. The details about the three application files are as follows: Main file: The file used for booting by default. The default file name is main.bin and the file type is M. Backup file: The default file name is backup.bin and the file type is B. The system uses the backup file when it fails to boot using the main file. Secure file: The default file name is secure.bin and the file type is S. The system uses the secure file when it fails to boot using the backup boot file. If the system fails to boot using the secure boot file, it prompts a boot failure. NOTE: The application files for system boot can be type M, B, and S, but not type N (namely, types other than type M, B, or S). You can modify the name of an application file in storage after the application file is loaded. You cannot modify the type of a type S application file, but you can modify the type of a type M, B, or N application file using the BootWare menu or using commands after the application file is loaded. The secure file is the last resort for system boot. You can download it in the BootWare menu and must name it secure.bin. However, you cannot modify the type of this file or change the type of other files to S. If you change the name of the secure file with the rename command after system boot, the file is removed from the Flash memory and you need to download it again. You can store type M, B, S files in storage devices, but only one for each type in each storage device. For example, if a type M+B file exists in the Flash memory, there will be no type M or B file. If you change the type of a file to B, the M+B file will become a type M file. Configuration files The configuration files store configuration information of the router. 35

43 By default, the system defines three configuration files for booting: main, backup, and default file. If the three configuration files are loaded in a storage device, the system selects them in sequence until the router is successfully loaded. To change the sequence of these configuration files or modify them, refer to Maintaining Application and Configuration Files on page 55. The details about the three configuration files are as follows: Main configuration file: The configuration file used for booting by default. The file type is M. Backup configuration file: The file type is B. The system uses the backup configuration file when it fails to boot using the main configuration file. Default configuration file: The file type can be M, B, or N. The system uses the default configuration file when it fails to boot using the backup configuration file. If the system fails to boot using the default configuration file, it boots with null configuration. The name of the default configuration file varies with router brands. The main and backup configuration operations on the default configuration file are the same as those on common configuration files. NOTE: The configuration file for system boot can be a main configuration file, a backup configuration file, or default configuration file of type N, but not non-default configuration file of type N (namely, neither type M nor type B). You can modify the file name of a configuration file in the Flash memory using a command after the configuration file is loaded. You cannot modify the type of the default configuration file, but you can modify the type of a type M, B, N configuration file in the BootWare menu, or using commands after the configuration file is loaded. You can store type M and B configuration files in the flash memory, but only one for each. For example, if a type M+B configuration file exists, there will be no type M or B file. If you change the type of a configuration file to B, the M+B configuration file will become a type M file. CAUTION: A file name can contain at most 64 characters (including drive letter and a string terminator). If the drive letters are FLASH:/, the file name can contain at most [ ] = 56 characters; otherwise errors will occur in file operation. Typically, a file name is recommended to be less than 16 characters. Extended ASCII characters (ASCII>=128) and invisible characters (ASCII<33) should not appear in a file name. The following characters should not appear in a file name:,,?, \, space, *,, <, /, :, >, and ~. The dot. can appear in a file name, but not at the head or the end of the file name. Two consecutive dots are not allowed. Software Maintenance Methods Upgrade BootWare and an application using the XModem protocol through a serial port. Upgrade an application from a TFTP/FTP server through an Ethernet interface in BootWare. Upload/download an application and configuration file from a TFTP/FTP server via command lines. 36

44 NOTE: The BootWare program is upgraded together with the Blinux application program. You do not need to upgrade the BootWare separately. When upgrading the Blinux program, the system checks whether the running BootWare version is consistent with that in the updating host application program. If inconsistent, the system asks whether to upgrade the BootWare. If you make no choice within one second, the system upgrades the BootWare automatically. When the flexible interface platform (FIP) starts, it automatically checks the running BootWare version. If the current version is inconsistent with the version used on the FIP, the system upgrades the BootWare automatically. Check the current version of BootWare and application program before upgrade. For the version configuration information, see the corresponding Release Notes. Figure 32 Upgrade flowchart for BootWare and Comware under the Comware V5 environment Start Comware version Upgrade Comware? N Choose correct Comware Y Choose upgrade mode Via network interface Xmodem upgrade TFTP upgrade FTP upgrade Upgrade End Maintaining Application Program and Configuration Through Command Lines After the router is booted, you can upgrade and back up an application program, and back up and restore configurations through command lines. 37

45 Maintaining the Router Through TFTP Server In the TFTP service, the router is TFTP client and the file server is the TFTP server. You can enter commands on the terminal to upload or download configuration files or application programs to or from the file server. Setting up a configuration environment Set up a hardware environment (refer to Upgrading an Application Program Through an Ethernet Interface on page 47 for details), and point the server path to the directory where the file is stored. Figure 33 Network diagram for maintenance through command lines Configure the IP addresses of both sides on the same network. For example, the IP address of the TFTP server is set to , and that of the Ethernet interface connected to it (Ethernet 0/0 in this example) is set to Use the ping command to check whether the connection successful. Backing up and restoring application programs and configuration files After setting up the environment, perform the following operations on the console terminal: Use the dir command to view the files in the current file system: <SYSTEM>dir Directory of flash:/ 0 -rw Jan :14:35 main.bin 1 -rw Jan :12:23 config.cwmp 2 -rw- 139 Jan :05:39 system.xml 3 -rw- 800 Jan :12:28 startup.cfg KB total (15921 KB free) <SYSTEM> Use the following command to upload the startup.cfg file to the TFTP server and save it as startup.bak: <SYSTEM>tftp put startup.cfg startup.bak File will be transferred in binary mode 38

46 Sending file to remote tftp server. Please wait... \ TFTP: 1045 bytes sent in 0 second(s). File uploaded successfully. Use the following command to download the startup.cfg file from the server to the router: <SYSTEM>tftp get startup.cfg startup.cfg The file startup.cfg exists. Overwrite it?[y/n]:y Verifying server file... Deleting the old file, please wait... File will be transferred in binary mode Downloading file from remote tftp server, please wait...\ TFTP: 1045 bytes received in 0 second(s) File downloaded successfully. If a startup.cfg file already exists in the router, the system prompts you whether to overwrite it. You can type Y or y to overwrite it. Upgrading the application programs After setting up the environment, perform the following operations on the device (the application name is msr.bin for example): Use the save command to save the current configuration: <SYSTEM>save The current configuration will be written to the device. Are you sure? [Y/N]:y Please input the file name(*.cfg)[flash:/startup.cfg] (To leave the existing filename unchanged, press the enter key): Use the dir command to view the application files and the available space of the CF card (ensure that the CF card has enough space to store a new application): <SYSTEM>dir Directory of flash:/ 0 -rw Jan :14:35 main.bin 1 -rw Jan :12:23 config.cwmp 2 -rw- 139 Jan :05:39 system.xml 3 -rw- 800 Jan :12:28 startup.cfg KB total (15921 KB free) <SYSTEM> Download the application msr.bin to the CF card of the device through TFTP: <SYSTEM>tftp get msr.bin File will be transferred in binary mode Downloading file from remote TFTP server, please wait...\ TFTP: bytes received in 34 second(s) File downloaded successfully. Use the boot-loader command to set the startup file for the next startup to msr.bin: <SYSTEM>boot-loader file flash:/msr.bin main This command will set the boot file. Continue? [Y/N]:y 39

47 The specified file will be used as the main boot file at the next reboot on slot 0! <SYSTEM> Use the display boot-loader command to view the startup file information of the device: <SYSTEM>dis boot-loader The boot file used at this reboot: flash:/main.bin attribute: main The boot file used at the next reboot:flash:/msr.bin attribute: main Failed to get the backup boot file used at the next reboot! Failed to get the secure boot file used at the next reboot! <SYSTEM> Make sure that the configured startup file is correct, and then use the reboot command to reboot the device: <SYSTEM>reboot Start to check configuration with next startup configuration file, please wait...done! This command will reboot the device. Current configuration may be lost in next startup if you continue. Continue? [Y/N]:y After the device is rebooted, use the display boot-loader command to view the startup file information of the device to make sure that the current application of the device is msr.bin. CAUTION: When you back up a file, the file will directly overwrite the one with the same name on the server. The backup configuration file can be modified by a text editor. You can change the configuration by downloading the modified configuration file and the modification takes effect after you reboot the router. Similarly, you can also upgrade the main application file by downloading a new application file to overwrite the original main application file. The above operations are performed in user view. Before upgrading an application, save the current configuration of the device. When upgrading an application, use the dir command to view the size of the downloaded file and whether the file is the same as that on the server to ensure that the application is complete and correct. Maintaining the Router Through FTP Server Maintaining the router serving as the FTP server File Transfer Protocol (FTP) is an application-layer protocol in the TCP/IP protocol suite. It is mainly used for file transfer between remote hosts. Over TCP, FTP provides reliable and connection-oriented data transfer service, but does not provide any access authorization and authentication mechanism. In the FTP service, the router can serve as the FTP server. You can run the FTP client to log in to the router access files on the router. Before using FTP, you need to install the FTP client. No FTP client is shipped with the H3C MSR 20-1X routers. In the following example, the FTP client application program is the built-in Windows XP FTP client. Step1 Set up a hardware maintenance environment, as shown in the following figure: 40

48 Figure 34 Maintain the router serving as the server Ethernet cable Router TFTP/FTP Server Console cable PC TFTP/FTP Client Configure the IP addresses of both sides on the same network. In this section, the IP address of the FTP server (PC) is set to , and that of the connected Ethernet interface on the router (Ethernet 0/0) is set to Use the ping command to check the connectivity. Step2 Enable the FTP service. After configuring authentication and authorization, you can enable the FTP service. The FTP server supports multi-user access. Upon receiving the request from a remote FTP client, the FTP server executes an action accordingly and returns the execution result to the client. Use the following command to enable the FTP service: [SYSTEM]ftp server enable % Start FTP server Add an authorized username and password: [SYSTEM]local-user guest [SYSTEM-luser- guest]service-type ftp [SYSTEM-luser- guest]password simple Step3 Maintain the router. After enabling the FTP service and configuring the username and password, you can enable the FTP client on the PC. In the following example, the FTP client application program is the built-in Windows XP FTP client. Type ftp in the DOS window, and the system prompt is changed to ftp>: C:\Documents and Settings\Administrator>ftp ftp> ftp> open Connected to FTP service ready. User ( :(none)): guest 331 Password required for guest Password: 230 User logged in. 41

49 After you correctly enter the username and password, the system prompts login success. You can then maintain the router, for example, modify transmission mode and local path, and back up files. In this example, the main.bin file on the router is copied to the PC. ftp> binary 200 Type set to I. ftp> lcd c:\temp Local directory now C:\temp. ftp> get main.bin main.bin 200 Port command okay. 150 Opening BINARY mode data connection for main.bin. 226 Transfer complete. ftp: bytes received in 16.81Seconds Kbytes/sec. Use the following command to recover the backup file to the router: ftp> put main.bin main.bin 200 Port command okay. 150 Opening BINARY mode data connection for main.bin. 226 Transfer complete. ftp: bytes sent in 8.29Seconds Kbytes/sec. ftp> quit 221 Server closing. Maintaining the router serving as a client You can also maintain the router file system by setting up an FTP environment where the router serves as an FTP client. Step1 Set up a maintenance environment. Figure 35 Maintain the router serving as a client The router serves as the client, while the PC running FTP server program serves as the FTP server. Set the FTP server path and add username and password for the router. 42

50 Configure the IP addresses of both sides on the same network. In this section, the IP address of the FTP server is set to , and that of the connected Ethernet interface on the router (Ethernet 0/0 in this example) is set to Use the ping command to check the connectivity. Step2 Maintain the router through the terminal connected with the console interface of the router. The following gives an example: <SYSTEM>ftp Trying Press CTRL+K to abort Connected to Com 3CDaemon FTP Server Version 2.0 User( :(none)):guest 331 User name ok, need password Password: 230 User logged in [ftp] Use the following commands to maintain the router. Here, the get and put commands are used to restore and back up files. [ftp]get main.bin main.bin flash:/main.bin has been existing. Overwrite it?[y/n]:y 200 PORT command successful. 150 File status OK ; about to open data connection 226 Closing data connection; File transfer successful. FTP: byte(s) received in second(s) K byte(s)/sec. [ftp]put main.bin main.bin 200 PORT command successful. 150 File status OK ; about to open data connection 226 Closing data connection; File transfer successful. FTP: byte(s) sent in second(s) Kbyte(s)/sec. [ftp]quit 221 Service closing control connection After an application is uploaded to the device, you can use the boot-loader command to upgrade the device. For the upgrade procedure, refer to Upgrading the application programs on page 39.

55 Configuring Ethernet Interface Parameters Before upgrading an application program through an Ethernet interface, we need to configure the Ethernet interface on the router as follows: Enter 3 in the BootWare menu to enter the Ethernet interface submenu. Then, enter 5 to enter the change Ethernet parameter submenu: =========================<ETHERNET PARAMETER SET>========================= Note: '.' = Clear field. '-' = Go to previous field. Ctrl+D = Quit. ========================================================================== Protocol (FTP or TFTP) :tftp ftp Load File Name :host : Target File Name :target : Server IP Address : Local IP Address : Gateway IP Address : FTP User Name :user FTP User Password :password Table 24 Ethernet parameters settings description Parameter '.' = Clear field '-' = Go to previous field Ctrl+D = Quit Protocol (FTP or TFTP) Load File Name Target File Name Server IP Address Local IP Address Gateway IP Address FTP User Name FTP User Password Description To clear the current field, input a (.) and then press Enter. To go to the previous field, input a hyphen (-) and then press Enter. The shortcut key combination for exiting the parameter configuration page is Ctrl+D. Select a transmission protocol, FTP or TFTP. Name of the source file, which must be consistent with the actual name of the file to be downloaded. Name for the target file to be saved. By default, it is the same as the name of the source file on the server. IP address of the FTP/TFTP server. To set a mask, separate the IP address from the mask with a colon (:), for example, :24. IP address of the local end, that is, the IP address of the FTP/TFTP client. Configure the gateway IP address if the server and the client are not on the same network segment. This option is not available for TFTP. This option is not available for TFTP. 48

56 NOTE: Upon upgrade failure, the system prompts Loading failed. In this case, please reboot the router to validate the reset IP address. Only Ethernet 0/0 can be used for upgrading an application program in the MSR 20-1X routers through an Ethernet interface. Upgrading Procedure Trivial File Transfer Protocol (TFTP), a protocol in the TCP/IP protocol suite, is used to transfer trivial files between clients and the server. It provides not-so-complex and low-cost file transfer services. TFTP provides unreliable data transfer services over UDP and does not provide any access authorization and authentication mechanism. It employs timeout and retransmission to guarantee the successful delivery of data. The TFTP software is much smaller than the FTP software in size: File Transfer Protocol (FTP) is an application-layer protocol in the TCP/IP protocol suite. It mainly transfers files among remote hosts. Over TCP, FTP provides reliable and connection-oriented data transfer service but does not provide access authorization and authentication mechanism. Step1 Set up an upgrade environment. Figure 36 Set up a TFTP/FTP upgrade environment Connect Ethernet 0/0 to a PC with a crossover cable. Start the TFTP/FTP program on the PC, and set the path of TFTP/FTP server to directory of the application program. You need to set username and password if FTP server is used. CAUTION: No TFTP/FTP Server is shipped with the MSR 20-1X routers. Step2 Modify Ethernet interface parameters. For details, refer to Configuring Ethernet Interface Parameters on page 48. Step3 Enter 3 in the main BootWare menu to enter the Ethernet Interface submenu. For example, when upgrading the main application program, enter 2: 49

57 Loading Done! bytes downloaded! Updating File flash:/update.bin Step4 Enter 0 to return to the main BootWare menu. Enter 1 to boot the system from the Flash memory. Step5 Set the upgraded application program to the main application file, namely, the default boot file of the system. Enter 4 when the above information appears. ==============================<File CONTROL>============================== Note:the operating device is flash <1> Display All File(s) <2> Set Application File type <3> Set Configuration File type <4> Delete File <0> Exit To Main Menu ========================================================================== Enter your choice(0-4):2 Enter the file control submenu and enter 2 to set the application file type.

Step6 Enter 0 to return to the main BootWare menu. Enter 1 to boot the system from the Flash memory. 50

58 CAUTION: If the input file name is the same as the original one in the Flash memory, the system prompts that The file is exist, will you overwrite it? [Y/N]. Enter Y to overwrite the original file. The new application program file will then overwrite the original file of this type, ensuring the uniqueness of the application program on the device. Make sure the available space in the memory is sufficient. Or, the system prompts The free space isn't enough!. The file updated will directly overwrite the original file of this type to become the only application program. The file downloaded here will overwrite the original M file and become the main boot program. For details of file types, refer to Files Managed by the Router on page 35. You can set the main or backup attribute only for the startup file in the root directory of the device. Upgrading BootWare Through Ethernet Interface You can also upgrade the BootWare through Ethernet interface. Enter 4 in the BootWare submenu, and the system displays: ==================<BOOTWARE OPERATION ETHERNET SUB-MENU>================== <1> Update Full BootWare <2> Update Extend BootWare <3> Update Basic BootWare <4> Modify Ethernet Parameter <0> Exit To Main Menu ========================================================================== Enter your choice(0-4): Before upgrading, enter 4 in the menu to configuring Ethernet parameters. For details, refer to Configuring Ethernet Interface Parameters. Then you can select to upgrade full BootWare, extended BootWare, or basic BootWare. Upgrading BootWare Through Serial Interface Use XModem to upgrade BootWare through a serial interface. XModem Protocol Overview To upgrade the BootWare and application program through a serial interface, use the XModem protocol. XModem is a file transfer protocol widely used for its simplicity and good performance. Modem transfers files through serial interfaces. It supports transmission of packets in 128 bytes and 1 KB, error check (checksum and CRC), and error retransmission (generally the maximum number of retransmission attempts is 10). XModem transmission is completed by the cooperation of a receiver and a sender. The receiver sends a negotiation message to the sender to negotiate an error check method. After the negotiation, the sender starts to transmit data packets. After a complete packet is received, the receiver checks the packet using the agreed method. 51

59 If the check is passed, the receiver sends an acknowledgement message to the sender. Upon receiving the message, the sender continues to send the next packet. If the check fails, the receiver sends a negative acknowledgement message to the sender. Upon receiving the message, the sender retransmits the packet. Modifying Serial Interface Parameters Sometimes, we need to increase the baud rate of a serial interface to save software upgrade time, or lower the baud rate to guarantee transmission reliability. This section describes how to adjust the baud rate of a serial interface. Enter 2 in the main BootWare menu to enter the serial interface submenu. Then, enter 5 and the system prompts for changing a baud rate. ==============================<BAUDRATE SET>============================== Note:'*'indicates the current baudrate Change The HyperTerminal's Baudrate Accordingly <Baudrate Avaliable> <1> 9600(Default)* <2> <3> <4> <5> <0> Exit ========================================================================== Enter your choice(0-5): Select a proper baud rate, 5 for bps for example. The following prompt appears: Baudrate has been changed to bps. Please change the terminal's baudrate to bps, press ENTER when ready. Since the baud rate of the serial interface on the router is changed to bps, whereas the terminal baud rate remains 9600 bps, they cannot communicate with each other. Change the baud rate on the console terminal to the one selected for downloading software. Perform the following configurations on the console terminal: Figure 37 Disconnect terminal Select File > Properties, and press Configure to change the baud rate to bps: 52

60 Figure 38 Modify baud rate Select Call > Call to establish a new connection. Figure 39 Establish a new connection Press Enter to view the current baud rate and return to the previous menu. The system displays: The current baudrate is bps NOTE: Restore the baud rate in the HyperTerminal to 9600 bps after upgrading the BootWare. This ensures that the information can be displayed on the console terminal after system boot or reboot. Upgrading BootWare First, enter 7 in the main BootWare menu (refer to Main BootWare Menu on page 43) to enter the BootWare operation submenu, through which all BootWare operations are performed. For details, refer to BootWare Submenus on page 45. The following example illustrates how to upgrade the full BootWare: 53

61 Enter 3 in the BootWare operation menu. The system displays: ===================<BOOTWARE OPERATION SERIAL SUB-MENU>=================== <1> Update Full BootWare <2> Update Extend BootWare <3> Update Basic BootWare <4> Modify Serial Interface Parameter <0> Exit To Main Menu ========================================================================== Enter your choice(0-4): Enter 1, and the system displays: Please Start To Transfer File, Press <Ctrl+C> To Exit. Waiting...CC Select Transfer > Send file in the HyperTerminal window. The following window appears: Figure 40 Send file dialog box Click Browse to select the application program file to be downloaded, and select XModem for the Protocol field. Then click Send. The following interface appears: Figure 41 Sending file interface Upon completion of downloading, the following information appears, indicating that download and upgrade succeeds: Download successfully! bytes downloaded! Change the baud rate of the console terminal from bps to 9600 bps, and then reboot the router. 54
