4 3 Features summary The NLMAINUNIT-2U-E is REMOTELY configured, controlled and monitored by the Netshield SNMP based Management information System. This software uses the SNMP protocol over a LAN connection to communicate with all the NLMAINUNIT-2U-E units connected to the network. ALWAYS WATCHING - With the SNMP based management and configuration interface, IT professionals can monitor, regulate and manage power to nearly every piece of equipment in data centres. Other management information systems should be able to interface with the NLMAINUNIT-2U-E with the SNMP protocol. The Surge Protection System offers the user a mains surge protecting solution and optional data protecting modules for external telecom data lines. ( eg. X.21, Ethernet, ADSL and E1.) The main function of the NLMAINUNIT-2U-E is to supply and monitor the NLPDU which supplies protected power to the user s servers, switches, routers. The NLPDU offers additional protection against lightning and surges. The NLMAINUNIT-2U-E also has the ability to measure power feed information like: Voltage (V), Current (A), Power (W), Accumulated Power (kwh) and Temperature ( C) The NLPDU utilizes power meter probes enabling the control, measure and indication of fault conditions on 230V AC appliances ranging from servers to air conditioners. Each individual power segment connected through the NLPDU can be monitored individually and set to rapidly react automatically (trip or switch-off power feed) against any dangerous conditions that could damage equipment in the data centre or equipment cabinet. Functional and alarm conditions are indicated on the front panel mounted LCD of the NLMAINUNIT-2U-E. The system utilizes a minimum of 2U of space within a standard 19inch equipment cabinet. In order to prevent initial overloads, by in-rush current during equipment power-up, the system provides the ability to power up device clusters in a pre-determined sequence. This causes a more regulated power influx and gives system administrators the option to turn on certain device clusters before others. In the event of a remote server problem or nonresponsive system, servers and network equipment can be rebooted by a forcing a reboot through a remote controlled power off/on cycle. 2

8 6.3 NLPDU Ports Protected 230VAC 16A Protected 230VAC 32A Unprotected 230VAC input 32 A RS485 ports Protected 230VAC input 7 Installation Unpack the units from the packaging. Install the MAINUNIT at the front of the 19 cabinet with standard cage screws and cage nuts. (Normally installation close to the bottom of the cabinet work the best, because of the mains power feed position) Install the NLPDU at the back of the cabinet, if possible. Otherwise install the NLPDU on top of the NLMAINUNIT. Before mains power connections, make sure that the power is switched off at the circuit breakers. Connect the power feed of the NLMAINUNIT to a mains dedicated wall box. Connect the two power feeds of the NLPDU to mains plugs capable of handle at least 240Vac. (Normally a 32A HUBBLE connector and plug are used, see Block diagram below) Connect devices like computers, printers etc. on any of the sixteen 10A kettle-like connectors on the protected / monitored outlets of the PDU. (Remember not to connect a device that draws more than 10A on a specific connector and make sure that accumulated consumption through all the 10A cables / plugs is not more than 16A. The total current capability of the NLMAINUNIT is 16A) Connect high energy consumption devices like Disk-Arrays, Cisco-Kits etc. on any of the two banks of four 16A connectors. (Remember not to connect a device that draws more than 16A on a specific connector and make sure that the accumulated consumption through all the 16A cables / plugs is not more than 32A. The total current capability of each PROBE inside the NLPDU is 32A, giving the capability of 2 x 32A = 64A) When all the mains wiring are done and safe, switch on the mains at the circuit breakers. 6

9 At the back of the NLMAINUNIT connect the RS485 bus RJ-45 connector (Note the sticker on the back of the unit) to one of the PROBE RJ-45 connectors with a standard 1:1 RJ-45 patch lead. Connect the Management port with a standard 1:1 patch lead to a RJ-45 point on the network. The default IP address is Once on the network telnet to the unit using the IP address port Change the IP address of the NLMAINUNIT in menu option 0. Change the SNMP settings and manager IP address in menu option 1. Install the Netshield Manager program and scan for new devices. 8 System information 8.1 NLMAINUNIT-2U-E The 2U mountable unit is AC powered and typically supplies the power to a 19 cabinet, thus protecting the user s servers, switches, routers etc. from lightning and surges. The Surge Protection System has a manageable port where the user can configure and read a variety of settings via the SNMPV1 protocol. The SPS unit has a Liquid Crystal Display (LCD) where it displays most of the unit and its remote probe energy information and external data protection statuses. With the two tactile switches the user can switch the mains to the load on or off, scroll through the menus and clear the accumulative power usage (kwh) NLMMAINUNIT Buttons The NLMAINUNIT-2U-E has two buttons located at the front of the unit. The left button (MENU) will switch on the display backlight and scroll through the menus and the right button (TRIP) will switch the mains on or off depending on the previous state of the mains. When the user is in one of the PROBE Menus and the trip button is pressed the appropriate PROBE will be switched on or off in any of the other menus the MAIN unit will be switched on or off. When both the button are pressed the accumulated power measurement will zero Graphic Display The main / default screen indicates the time, date, and temperature inside the main unit, the site name ( and the unit serial number. These indicators can be configured via the SNMP interface. NLMAINUNIT-2U-E TIME: 13:45:05 DATE: 23/09/2008 TEMP: C S/N: SYSTEM OK NLMAINUNIT-2U-E TIME: 13:45:05 DATE: 23/09/2008 TEMP: C S/N: HPWR-PROBE1 MAINS ERR NLMAINUNIT-2U-E TIME: 13:45:05 DATE: 23/09/2008 TEMP: C S/N: SP-SYSTEM MAINS TRP When there are no problems with the main unit or any of the probes, the main screen will indicate SYSTEM OK. There are several system error that and when a system error has 7

10 occurred it will be displayed on the bottom of the default screen / menu. The following errors might occur: SP-SYSTEM MAINS TRP: This indicates that on the main unit, the power has tripped because the current drawn has exceeded the limit. Increase the current trip limit if applicable and switch the power back on with the TRIP button or via SNMP. HPWR-PROBE1 MAINS TRP: This indicates that on the Power Probe1 module, the power has tripped because the current drawn has exceeded the limit. Increase the current trip limit if applicable and switch the power back on with the TRIP button or via SNMP. HPWR-PROBE2 MAINS TRP: This indicates that on the Power Probe2 module, the power has tripped because the current drawn has exceeded the limit. Increase the current trip limit if applicable and switch the power back on with the TRIP button or via SNMP. SP-SYSTEM MAINS ERR: This indicates that the surge protection circuitry on the main unit is faulty and that the unit is not protecting the attached equipment from lightning and surges. This will typically happen after the event of hard lightning. When this happens send the units in for repairs. HPWR-PROBE1 MAINS ERR: This indicates that the surge protection circuitry on the Power Probe1 module is faulty and that the unit is not protecting the attached equipment from lightning and surges. This will typically happen after the event of hard lightning. When this happens send the units in for repairs. HPWR-PROBE2 MAINS ERR: This indicates that the surge protection circuitry on the Power Probe2 module is faulty and that the unit is not protecting the attached equipment from lightning and surges. This will typically happen after the event of hard lightning. When this happens send the units in for repairs. MAINS SURGE FAILURE: When enabled, (see CONFIG MENU) this indicates that the external mains surge protection module (in distribution box) has failed, typically after the event of lightning. Replace the module. When the user press the MENU button at the front of the main unit, initially the backlight of the display will switch on for 7 seconds. When the user press the MENU key within the 7 second period the display will switch to a different menu indicating the measurement of the MAINUNIT as follows: SP SYSTEM MAINS ON VOLT: CURRENT: POWER: ACC POWER: 30 C 50.00Hz V A 283 W 1234 kwh ENTER KEY FOR PROBE1 8

11 The SURGE PROTECTION SYSTEM menu indicates the mains line frequency, the unit temperature and the energy statuses. The Voltage measurement will measure the input mains and can vary between 0 300Vac. The Current measurement measures the load current up to 20A but will trip when it reaches 16A. The Power measurement is a indication of the apparent energy consumed by the load. The accumulated power will roll over to zero when it reaches kwh. Pressing the MENU button, while the backlight is ON, will change the display menu to the first probe inside the NLPDU unit. HIGH PWR PROBE1 HIGH PWR PROBE1 30 C MAINS ON _ PROBE1 NOT AVAILABLE. VOLT: CURRENT: POWER: ACC POWER: V A 5905 W 5678 kwh ENTER KEY FOR PROBE2 ENTER KEY FOR PROBE2 When there is not a probe available, the menu will display PROBE1 NOT AVAILABLE But when the probe is present the menu will indicate all the same type of measurements as the SURGE PROTECTION SYSTEM menu. The same rules apply for the second HIGH POWER PROBE. HIGH PWR PROBE2 HIGH PWR PROBE2 30 C MAINS ON _ PROBE2 NOT AVAILABLE. VOLT: CURRENT: POWER: ACC POWER: V A 7360 W 8936 kwh ENTER KEY FOR MODULES ENTER KEY FOR MODULES Pressing the MENU button, while the backlight is ON, will bring the display to the DATA PROTECTION menu.

CONFIG SET UNIT BACKLIGHT ON s _ TRIPTIME 55 ms _ EXT PROTECT ON _ CONFIG SET UNIT BACKLIGHT ON s _ TRIPTIME 55 ms _ EXT PROTECT ON _ CONFIG SET UNIT BACKLIGHT ON s _ TRIPTIME 55 ms _ EXT PROTECT ON _ ENTER FOR TRIP ENTER FOR EXT PROTECT ENTER KEY TO RETURN The CONFIG menu configures the BACKLIGHT on-time of the display. The display has a time-out setting of 10 milliseconds up to 1 minute and a permanent ON setting. When the BACKLIGHT setting is highlighted one can toggle through the backlight time-out setting options with the trip button. When entering the menu button, the TRIPTIME will be highlighted. In this mode the TRIP button will toggle through the trip-time is milliseconds. The trip-time is defined as the time to trip in milliseconds when the maximum current is exceeded, settable via the SNMP interface (1Amp to 16Amp). The default is 55 milliseconds. When entering the menu button, the EXT PROTECT will be highlighted. Here the user can change the setting to ON and OFF. By setting the EXT PROTECT to ON the unit will check if the Mains Surge Protection module is still functional. If the module fails the unit will send out a SNMP trap and display a warning on the default screen. If the setting is switched off no trap will be send and no warning will be displayed about the module on the default screen. By pressing the MENU button while the backlight is ON, the MENU will change to the default screen. 10

13 8.2 NLPDU High power probes Inside the NLPDU are two High Power Probes fitted. The High Power Probe offers the user a mains surge protecting solution in the telecoms, commercial and industrial industry. The High Power Probe has a manageable interface where the user can configure and read a variety of settings using the Netshield Sensor Protocol (NSP). With the onboard tactile switch the user can switch the mains on or off and clear the accumulative power usage (kwh) NLPDU Button The NLPDU has one button for each of the two HIGH POWER PROBES inside the unit, located at the back of the NLPDU unit. When the user presses a TRIP button of a PROBE, the mains of that PROBE will switch on or off depending of the previous state. When the button is in a pressed position for 6 seconds the accumulated power measurement zeros. 11

14 9 Netshield SNMP Management software Monitor One The NLMAINUNIT-2U-E is remotely configured, controlled and monitored by the Netshield SNMP based management information system (Monitor One). This software uses the SNMP protocol over a LAN connection to communicate with all the NLMAINUNIT-2U-E units connected to the network. There are over 800 configurable settings to control the NLMAINUNIT-2U-E unit. These settings range from Site name through to environmental limit settings. Other management control software should also be able to interface with the NLMAINUNIT-2U-E unit with the SNMP protocol. 9.1 Installation and setup of Netshield SNMP Management Software (Monitor One) Install the software on any personal computer that has access to the local network or the internet. The software is available for download on the netshieldsa.com website A complete manual of the management software (Monitor One) is available for download on the netshieldsa.com website The following is an overview of the management software (Monitor One) 12

All the reading object identifiers (Voltage, Current, Power, ACC Power, Temperature, Strip status and Mains protection status) of the NLMAINUNIT and the two PROBES inside the NLPDU unit can be found under their corresponding subtree. At the bottom of the two HighPowerProbe subtrees are the probe presence indicators. A 1 will indicate that the unit is up and running and a 0 indicates that the probe is not connected. The three available data protection modules statuses are under the DataProtectionModules subtree. Indicating the presence, control and the indicate statuses. 9.4 Settings Subtree Under the settings subtree are the three surge protection unit setting (NLMAIN, PROBE1 and PROBE2). In these subtrees are the Out of Limits settings. These are the values where the system will send out SNMP traps to indicate critical conditions. The current trip setting, 1-16A for the MAINUNIT or 1-32A for the PROBES, is settable under the CurrentSettings subtree of each unit respectively. The mains can be switched on or off and the sitename can be changed under the Probe- / SPSsettings. The time and date of the system are also settable / readable in the SPSsettings subtree. Please take note: When 123 is set on the SPSRestoreDefaults, under the SPSsettings subtree, the NLMAINUNIT will discard the available probes allocated to the MAINUNIT. Use this setting only when new Probes replace old Probes. 18

21 The user can force if a probe should be enabled or disabled at the HPwrProbe1/2Presence by setting the integer number 1 for enable or 0 for disable via the SNMP interface. 9.5 Traps Subtree Under the Traps subtree the Object identifier SPSMessageString contains the message of the last trap that was sent to the manager system. If there is a communications error between the SNMP engine and the embedded system inside the MAINUNIT the trap SPSAlarmSerialCom will indicate it with a 1 otherwise the object identifier will indicate a Specifications 10.1 NLMAINUNIT-2U-E specifications Mains: Unit Input / Output Specifications: Category Minimum Nominal Maximum Units Input / Output Voltage: V(ac) Input Current: A(ac) Power Usage: W Output Current (load): A The unit has high surge handling capability with over current fusing and a visual fault indication on the unit s display.

24 10.3 NLMAINUNIT-2U-E & NLPDU Measurements The system measures the following and are displayed on the LCD: Category NLMAINUNIT NLPDU Units Voltage: V Current: A Apparent Energy: VA Accumulated Energy: kwh Temperature: ºC 11. Packaging list NLMAINUNIT-2U-E NLDPU Male to female power cord 12. Trouble Shooting Fault: The NLMAINUNIT can not be found on the IP network. Solution: Make sure the IP address is set to be static and in the same IP range. Connect to the NLMAINUNIT via TELNET with the default IP address: and change the IP address with menu option 0. Fault: The manager software can not detect the unit but a ping to the unit works. Solution: Make sure that the manager computer has a static IP address and that the manager IP address is set in the NLMAINUNIT SNMP settings via TELNET, menu option 1. Check the read and write community strings of the manager and the NLMAINUNIT. Default is public for the read community and private for the write community. Fault: The NLMAINUNIT does not detect the PROBES inside the NLDPU unit via the display or via the manager software. Solution: Do an address reallocation. Disconnect the RS485 cable between Probe1and Probe2 but make sure that the RS485 cable from the NLMAINUNIT and PROBE1 is still connected. Press and hold the TRIP button on both PROBES of the NLPDU for more than 16 seconds. 22

25 With the SNMP interface, expand the Setting subtree, the SurgeProtectionSettings subtree, the SPSSettings subtree and set 123 in the SPSRestoreDefaults object indentifier to release all the allocated Probe addresses. Switch off the mains power feed of both Probes inside the NLPDU. After 3 5 seconds switch on the power feeds again. The PROBE1 NOT AVAILABLE indication on the display should change and the energy information should be visible on the display. Connect the cable between the two Probes again and Probe2 should be registered on the NLMAINUNIT. Fault: The NTU does not pick up the data / clocks from the router or visa versa. Solution: Check the cable connections to the Data Protection Module. Make sure the Module is properly mated with the NLMAINUNIT. Check if the NTU / Router work when the input cable to the x.21 Data Protection Module is directly connected to the output cable. If it starts to work, the module is faulty. Not, one of the cables is faulty. Problem Probable cause Remedy 23
