Table 1 HP 6127XLG Blade Switch Series models Product code HP description RMN Alias B21 HP 6127XLG Ethernet Blade Switch HSTNS-BC65-N HP 6127XLG B22 HP 6127XLG Ethernet Blade Switch with TAA HSTNS-BC65-N HP 6127XLG TAA IMPORTANT: For regulatory identification purposes, the switches are assigned regulatory model numbers (RMNs). These regulatory numbers should not be confused with the marketing names HP 6127XLG and HP 6127XLG TAA, or the product codes B21 and B22. You can install the blade switch in the HP BladeSystem c7000 enclosure. The installation position in the enclosure in this document is only for illustration. For more information, see HP BladeSystem Enclosure Setup and Installation Guide. Preparing for installation WARNING! The blade switch is Class 1 laser device. Do not stare into any fiber ports when the blade switch has power. The laser light emitted from the optical fiber might hurt your eyes. To avoid any equipment damage or bodily injury caused by improper use, follow the enclosure safety recommendations. For more information, see HP BladeSystem Enclosure Setup and Installation Guide. CAUTION: Take ESD measures to avoid damaging the components. For more information, see HP BladeSystem Enclosure Setup and Installation Guide. Installing and removing the blade switch IMPORTANT: Do not use excessive force during the installation and removal processes. Remove the cables before removing the blade switch. If the blade switch does not install easily, make sure it is correctly oriented. To prevent dust from entering the system, install the interconnect blank into the interconnect bay after removing the blade switch. 1

6 Installing the blade switch 1. Wear an ESD wrist strap and make sure it makes good skin contact and is reliably grounded. 2. Remove the interconnect blank from the slot. Keep the removed interconnect blank for future use. 3. Unpack the blade switch. 4. Press the release tab (see callout 1 in Figure 1) and then pull the ejector lever to the open position (see callout 2 in Figure 1). Figure 1 Opening the ejector lever 5. Slide the blade switch into the interconnect bay (see callout 1 in Figure 2) until it touches the backplane. 6. Push the ejector lever to the closed position. (See callout 2 in Figure 2).

7 7. Verify that the Health LED is green after the blade switch starts up. If the Health LED is not green, check the installation. 8. Choose correct cables to connect to the ports on the blade switch. For more information about ports, see "Ports." For more information about cable installation, see "Connecting the blade switch to the network." Removing the blade switch 1. Wear an ESD wrist strap and make sure it makes good skin contact and is reliably grounded. 2. Press the release tab to open the ejector lever. 3. Pull the ejector lever outwards slowly to take out the blade switch. Connecting the blade switch to the network Precautions Make sure the fiber connector and fiber type match the transceiver module type. The fiber ports have shielded covers. Remove the shielded covers before using the fiber ports and keep them safely. Fiber interfaces must be installed with shielded covers when they are not in use. Fiber connectors must be protected under safe and reliable outer packing, and be fitted with dust caps. Fiber connectors must be installed with dust caps when they are not in use. Take care not to scratch their end face. Replace the dust cap if it is loose or polluted. Before connecting a fiber, use dust free paper and absolute alcohol to clean the end face of the fiber connector. You can brush the end face only in one direction. You also need to brush the end face of the fiber port. Never bend or curve a fiber when connecting it. For the QSFP+ module, you do not need to differentiate between the transmitter (TX) and receiver (RX) ports. For other types of transceiver modules, the Tx port on one end must connect to the RX port on the other end. Connecting the optical fibers WARNING! To avoid injury to your eyes, do not stare at the optical interfaces and optical fiber connectors when connecting optical fibers. You can install a transceiver module in a fiber port on the blade switch and then plug the fiber connector to the transceiver module. For more information about installing the transceiver module, see Pluggable SFP[SFP+][XFP] Transceiver Modules Installation Guide and Pluggable QSFP+ Transceiver Modules/Cables Installation Guide. To install a transceiver module into the port on the blade switch and the peer device: 1. Remove the dust cover of the fiber connector, and clean the end of the fiber connector. 2. Remove the dust plug of the transceiver module, plug one end of the optical fiber into the transceiver module, and plug the other end into the transceiver module in the peer device. 3

Verify the port LEDs for correct connection. For more information about LED status, see "LEDs." After you connect the blade switch to the network, use the ping or tracert command to test network connectivity. For more information about these two commands, see HP 6127XLG Blade Switch Series Network Management and Monitoring Command Reference. 4

9 Accessing the blade switch for the first time You can access the blade switch either by logging in through the OA module or through the console port. Logging in through the OA module To log in to the blade switch through the HP BladeSystem Onboard Administrator (OA) module: 1. Use a serial cable to connect the terminal (for example, a PC) to the serial port of the OA module. 2. Turn on the PC, run a terminal emulator program (for example, Windows XP HyperTerminal) on the PC, and set terminal parameters as follows: Bits per second 9,600. Data bits 8. Parity None. Stop bits Press Enter and the login information appears. 4. Enter the username and password. OA prompt information appears on the login interface. 5. Enter the connect interconnect <bay_number> command, where the bay number argument specifies the slot number of the blade switch. 6. Press Enter. When the command line prompt appears, you can configure the switch. For more information about the configuration, see "Configuring the blade switch." Logging in through the console port When you access the blade switch through the console port, you must use a console cable (see Figure 5) to connect a console terminal, for example, a PC, to the console port on the blade switch. A console cable is an 8-core shielded cable, with a crimped RJ-45 connector at one end for connecting to the console port of the blade switch, and a DB-9 female connector at the other end for connecting to the serial port on the console terminal. Figure 5 Console cable 5

Plug the DB-9 female connector of the console cable in the serial port of the PC. 2. Plug the RJ-45 connector of the console cable in the console port of the blade switch. IMPORTANT: Identify the mark on the console port and make sure that you are connecting to the correct port. Make sure a DB-9 female connector is available on the terminal. If not, prepare a converter. Figure 6 Connecting a console port to a terminal Setting terminal parameters To configure and manage the switch through the console port, you must run a terminal emulator program, HyperTerminal or PuTTY, on your configuration terminal. You can use the emulator program to connect a network device, a Telnet site, or an SSH site. For more information about the terminal emulator programs, see the user guides for these programs. The following are the required terminal settings: 6

11 Bits per second 9,600. Data bits 8. Parity None. Stop bits 1. Flow control None. Configuring the blade switch By default, the switch does not authenticate console login users. To increase system security and enable remote management: Configure a login authentication method, for example, Telnet, SSH, or NMS. Configure access services. Configuring an authentication method You can configure authentication on a user interface to control access to the switch. Table 3 describes the Telnet login authentication methods available for a VTY user interface. For more information about login authentication methods, see HP 6127XLG Blade Switch Series Fundamentals Configuration Guide. Table 3 Telnet login authentication methods Authentication method None Password Username and password Characteristics Easy to configure, insecure Easy to configure, secure, providing flat user management Complex to configure, secure, providing hierarchical user management Application scenarios Lab environments and extremely secure network environments Environments that do not need granular privilege management Environments where multiple operators cooperate to manage the switch Configuring the basic network settings An HP 6127XLG or HP 6127XLG TAA blade switch without any configuration will continuously attempt to obtain an IP address via DHCP. After obtaining an IP address, it downloads a configuration file based on DHCP options 67 and 150. To use the auto-configuration feature, see HP 6127XLG Blade Switch Series Fundamentals Configuration Guide. The switch can perform basic data forwarding immediately after connecting to a network. To implement more forwarding features, configure the basic network settings such as IP address, static route, and VLAN. For more information, see HP 6127XLG Blade Switch Series Configuration Guides. 7

13 Setting up an IRF fabric You can use HP Intelligent Resilient Framework (IRF) technology to connect and virtualize HP 6127XLG blade switches into a virtual switch called an "IRF fabric" or "IRF virtual device" for flattened network topology, and high availability, scalability, and manageability. Planning IRF fabric setup Determining the number of IRF member devices Choose HP 6127XLG blade switch models and identify the number of required IRF member switches, depending on the user density and upstream bandwidth requirements. The switching capacity of an IRF fabric equals the total switching capacities of all member switches. Identifying the master switch and planning IRF member IDs IRF member switches will automatically elect a master. You can affect the election result by assigning a high member priority to the intended master switch. For more information about master election, see HP 6127XLG Blade Switch Series IRF Configuration Guide. Determine which switch you want to use as the master for managing all member switches in the IRF fabric. An IRF fabric has only one master switch. You configure and manage all member switches in the IRF fabric at the command line interface of the master switch. Prepare an IRF member ID assignment scheme. An IRF fabric uses member IDs to uniquely identify and manage its members, and you must assign each IRF member switch a unique member ID. Planning IRF topology and connections You can create an IRF fabric in daisy chain topology, or more reliably, ring topology. In ring topology, the failure of one IRF link does not cause the IRF fabric to split as in daisy chain topology. Rather, the IRF fabric changes to a daisy chain topology without interrupting network services. You connect the IRF member switches through IRF ports, the logical interfaces for the connections between IRF member switches. Each IRF member switch has two IRF ports: IRF-port 1 and IRF-port 2. An IRF port goes up when you bind the first member physical port to it. When connecting IRF member switches, you must connect the physical ports of IRF-port 1 on one switch to the physical ports of IRF-port 2 on its neighbor switch. The following physical ports can be used for IRF connections: SFP+ ports and QSFP+ ports. For more information about the transceiver modules and cables available for the SFP+ and QSFP+ ports, see Table 10, Table 11, Table 12, and Table 13. Crosslink ports. A crosslink port is an internal port on a switch that connects to the switch in the adjacent horizontal interconnect bay in the C7000 enclosure. The HP 6127XLG or HP 6127XLG TAA switch has four crosslink ports: Port 17, Port 18, Port 19, and Port 20. By default, the four ports are 9

14 shut down to avoid loops. To create an IRF fabric on two switches by using crosslink ports, execute the undo shutdown command to bring up the crosslink ports with the same number on the switches. Figure 7 Connecting IRF member switches using crosslink ports Configuring basic IRF settings After you install the IRF member blade switches, power on the blade switches, and log in to each IRF member blade switch (see HP 6127XLG Blade Switch Series Fundamentals Configuration Guide) to configure their member IDs, member priorities, and IRF port bindings. For more information about configuring basic IRF settings, see HP 6127XLG Blade Switch Series IRF Configuration Guide. Connecting the physical IRF ports Connect the IRF member switches as planned. NOTE: Wear an ESD wrist strap when you connect cables or transceiver modules and fibers. For how to connect them, see Pluggable SFP[SFP+][XFP] Transceiver Modules Installation Guide and Pluggable QSFP+ Transceiver Modules/Cables Installation Guide. Accessing the IRF fabric to verify the configuration To verify the basic functionality of the IRF fabric after you finish configuring basic IRF settings and connecting IRF ports: 1. Log in to the IRF fabric through the console port of any member switch. 2. Create a Layer 3 interface, assign it an IP address, and make sure that the IRF fabric and the remote network management station can reach each other. 3. Use Telnet, web, or SNMP to access the IRF fabric from the network management station. (See HP 6127XLG Blade Switch Series Fundamentals Configuration Guide.) 4. Verify that you can manage all member switches as if they were one node. 5. Display the running status of the IRF fabric by using the commands in Table 4. Table 4 Displaying and maintaining IRF configuration and running status Task Display information about the IRF fabric Display all members configurations Command display irf display irf configuration 10

15 Task Display topology information about the IRF fabric Command display irf topology NOTE: To avoid IP address collision and network problems, configure a minimum of one multi-active detection (MAD) mechanism to detect the presence of multiple identical IRF fabrics and handle collisions. For more information about MAD detection, see HP 6127XLG Blade Switch Series IRF Configuration Guide. 11

16 Troubleshooting IMPORTANT: To prevent configuration loss, save the configuration each time you finish configuring a feature. For configuration recovery, regularly back up the configuration to a remote server Troubleshooting methods When your blade switch fails, you can use the following methods to troubleshoot the blade switch: At the CLI, use related commands to display system operating information, and locate the failures. Locate the failures according to the LED status on the blade switch. For more information, see "LEDs." View the system and port operating state through the OA module on the enclosure. For more information, see HP BladeSystem Enclosure Setup and Installation Guide. NOTE: If you cannot locate failures by following the guidelines in this chapter, contact HP Support. Collecting log and operating information IMPORTANT: By default, the information center is enabled. If the feature is disabled, you must use the info-center enable command to enable the feature for collecting log messages. Table 5 shows the types of files that the system uses to store operating log and status information. You can export these files by using FTP or TFTP. In an IRF system, these files are stored on the master device. Multiple devices will have log files if master/subordinate switchovers have occurred. You must collect log files from all these devices. To more easily locate log information, use a consistent rule to categorize and name files. For example, save log files to a separate folder for each member device, and include their slot numbers in the folder names. Table 5 Log and operating information Category File name format Content Common log logfile.log Command execution and operational log messages. Diagnostic log diagfile.log Diagnostic log messages about device operation, including the following items: Parameter settings used when an error occurs. Information about device startup errors. Handshaking information between member devices when a communication error occurs. 12

(Details not shown.) Collecting operating statistics You can collect operating statistics by saving the statistics to a file or displaying the statistics on the screen. When you collect operating statistics, follow these guidelines: Log in to the device through a network port (if any) instead of the console port. Network ports are faster than the console port. Do not execute commands during operating statistics collection. To ensure information completeness, HP recommends that you save the statistics to a file. To collect operating statistics: 1. Disable pausing between screens of output if you want to display operating statistics on the screen. Skip this step if you are saving statistics to a file. <Sysname> screen-length disable 2. Collect operating statistics for multiple feature modules. <Sysname> display diagnostic-information Save or display diagnostic information (Y=save, N=display)? [Y/N] : 3.
