:RUN NMMGR.PUB.SYS
2. Press the Open Config softkey twice and wait while NMMGR opens a configuration file.
3. Press
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 of group CONFIG.SYS.
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.
To Use UPS Monitor/iX Software
Once you have configured UPS devices on the system, they will automatically be monitored by the UPS
Monitor/iX software. This software causes the UPS devices to emulate the traditional battery backup method
of system powerfail handling and recovery.
The UPS Monitor/iX process behaves in one of two ways, depending on the system on which Release 5.0 or
later of MPE/iX has been installed:
• When installed on a system that has been configured with UPS devices, UPS Monitor/iX runs continually
while the system is up to monitor all of the UPS devices for power failure and any other hardware status
conditions. It reports these conditions to the system operator’s console via console messages and records
them in the system log file.
• When installed on an old system that does not use UPS devices, UPS Monitor/iX is launched at startup,
discovers that there are no UPS devices on the system, and terminates itself. In this case, the system uses
the existing battery backup method of system power failure protection.
NOTE UPS monitoring is event number 148 in the system log files. The default is ON (i.e., UPS
hardware conditions are recorded in the files) regardless of whether the system has UPS power
fail protection or not. In the latter case, when no UPS devices have been configured, the system
log files will receive and record two UPS-related messages each time the system starts: one
indicating that the UPS Monitor/iX process has been launched and a second message which
says that no UPS devices are found in the I/O configuration.
