Appendix B Configuring Your UPS
Introducing the UPS
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.
