A new method of power failure protection is available on the HP 3000 Series 9X8 system. Instead of battery backup units, they will have one or more HP model A2998A PowerTrust UPS (Uninterruptible Power Supply) devices.

Like the battery backup method of power failure, the UPS devices protect the HP 3000 system against the loss of work in progress in cases of utility AC power failures of up to fifteen minutes in duration. Furthermore, they have been designed to appear similar to the battery backup method which minimizes their effect on system operation and management procedures.

UPS devices offer two principal advantages over the battery backup method:

  • In a minimal UPS-based system, the degree of power failure protection is equivalent to that provided by the battery backup unit. You can, however, add more UPS devices to the system and provide reserve power to selected peripherals. Depending upon how much of the system is provided with UPS power, it can run a partial or full workload non-stop through limited periods of AC power failure.

  • The UPS contains a serial I/O communications interface that, in conjunction with UPS Monitor/iX software, notifies the system operator of any problems. Like the battery backup hardware that the UPS devices replace, a system-wide power failure recovery message is broadcast to all active user terminals and to the console upon the return of power following a failure. In addition to console messages, the UPS Monitor/iX software also posts a variety of status and warning messages to the system log files which you can review and analyze to evaluate system performance.

To configure a UPS device

You can use one of two configuration methods to add UPS devices to a Series 9X8 systems. For the first or only UPS, which is attached to the third serial port on the system's LAN/Console I/O interface card, you use NMMGR to set the data preconfigured in the default configuration group supplied with the FOS tape. You perform this procedure once, immediately after you install a new system. For additional UPS devices, which are attached to a DTC serial I/O port, you use NMMGR to supply all of the information necessary to configure the device(s). (As the final step in this second method, you will cross-validate the configuration files with SYSGEN.)

NOTE: Each UPS device, and only a UPS device, must have its device class name set to HPUPSDEV during I/O configuration. Otherwise, the UPS Monitor/iX software will not be able to initialize and communicate with the UPS device(s) correctly.

To configure the first UPS after an Install

After you have installed a new Series 9X8 system, you must "set" the UPS configuration data supplied in default configuration group. To configure the first UPS, do the following:

  1. Boot the system using the default configuration group.

  2. At the MPE prompt, start the NMMGR program. Enter:

       :RUN NMMGR.PUB.SYS

  3. Press the {{Open Config}} softkey twice and wait while NMMGR opens a configuration file.

  4. Enter a node name and press the {{Save Data}} softkey.

  5. Press the {{Go to DTS}} softkey to display the DTS configuration screen.

  6. Tab to the third field and enter the physical path of the LAN/Console I/O interface card, then press the {{Save Data}} softkey.

  7. Press the {{Go to UPS Port}} softkey and at the UPS Port screen, verify that the LDEV number is correct, the Parity Checking option is set to none, and the baud rate to 1200. Make any changes to this screen if it is necessary to correct the values.

  8. Press the {{Save Data}} softkey to save your UPS Port configuration. (Note that the upper right corner of the screen will change from Data: N to Data: Y.)

  9. Press {{Prior Screen}} twice and at the Main screen, press {{Utility}}.

  10. At the Utility screen, press {{Validate Link/DTS}} to cross-validate the DTC configuration with the SYSGEN configuration.

  11. Once validation is complete, press {{Prior Screen}} three times and at the Open Configuration File screen, press {{Exit Program}} to exit NMMGR.

  12. Reboot the system to make the new configuration effective.

  13. Turn power to the DTC hardware off and then on again to download the correct baud rate for the UPS port to the DTC hardware. (On some systems, cycling the power to a DTC may require you to unplug it and plug it in again.)

NOTE: If you don't know the path of the Console/LAN interface card, start SYSGEN's I/O configurator and at the io> prompt, use the LDEV command to check the path:
   io>LDEV LDEV=20

The console will be on an I/O path of the form XX/XX.0, such as 56/56.0. The UPS device that you are configuring will have a path of the form XX/XX.3 (for example, 56.3). Exit the I/O configurator and Sysgen and use this information in step 6.

To configure a UPS connected via a DTC port

All UPS devices on a Series 9X8 system other than the first one are connected to your computer system via a DTC port. You use the NMMGR program to add them to your system configuration using a procedure that is very similar to configuring user terminals.

To configure a UPS connected via a DTC, do the following:

  1. At the MPE prompt, start the NMMGR program. Enter:

       :RUN NMMGR.PUB.SYS

  2. Press the {{Open Config}} softkey twice and wait while NMMGR opens a configuration file.

  3. Press {{Go to DTS}} to enter the DTS configurator.

  4. Press {{Go to DTC}} and choose the appropriate DTC configurator for the system (DTC16ix, DTC16MX, DTC16, DTC48, etc.).

  5. Choose an available LDEV number for the UPS you are configuring, and determine which DTC port (DTC card number and port number) the UPS is connected to.

  6. Press the {{Config Card}} softkey to enter the DTC card configurator.

  7. Add each UPS by entering its logical device number in the Ldev field and UP10D12 in the Profile Name field. When you have added all UPS devices, press {{Save Data}}

  8. Press the {{Validate Link/DTS}} softkey to cross-validate the DTC configuration with the SYSGEN configuration.

  9. Once validation is complete, press {{Prior Screen}} until you see the Open Configuration File screen, and then press {{Exit Program}} to exit NMMGR.

    If you see a message that the NETXPORT subsystem has not been validated, ignore it and exit the program.

  10. Shut down the system.

  11. Turn power to the DTC hardware off and then on again to download the correct baud rate for the UPS port to the DTC hardware. (On some systems, cycling the power to a DTC may require you to unplug it and plug it in again.)

  12. Reboot the system to make the new configuration effective.
