Power Failing The Ups - HP PowerTrust A3589A Manual

Power Failing the UPS

Before forcing an AC input power failure to test the UPS and its communication with the
system, wait for the system to establish communication and initialize the UPS.
On a MPE/iX system, it takes the system about 30 seconds from the time it finishes
downloading the DTCs with their firmware to be ready to respond to UPS events. As the
system is finishing its boot up process, watch the system console for the message:
nmev #`00@234 dtmc c0000303 code download completed for DTC address 080009281E05.
Wait 30 seconds after that message appears, and then perform the power fail test.
For either HP-UX or MPE/iX systems, use this procedure to power fail a system:
1. Check that the system is not performing critical processes.
2. Use the wall breaker to cut the power for the circuit that is supplying power to the UPS.
Do NOT use the rear panel circuit breaker to power fail the system.
3. Wait one (1) full minute.
4. Verify that messages are displayed on the console.
5. Verify that the indicators are normal for battery power:

Attention
Alarm 1 beep
6. Use the wall breaker to return power to the UPS AC input circuit.
CAUTION
Do NOT pull the power cord. This would compromise the electrical fault
protection because it provides grounding.
