AC Power Query Test (#78)
This test queries either the server’s watchdog (via an Ethernet or USB interface)
or an MCC EPN’s Maintenance circuit pack for status of the cabinet’s AC power.

Result Description / Recommendation
1000 ABORT System resources required to run test are not available.
1. Retry the command at 1-minute intervals up to 5 times.

ABORT Response to the test request was not received within the allowable time
period.
1. Retry the command at 1-minute intervals up to 5 times.
2. If the test continues to ABORT with error code 2000, check for system
powering problems with the EPN’s A carrier. Resolve every AC-POWER
and CARR-POW alarm. Then, repeat the test.
3. If the test still ABORTs with error code 2000, check for and resolve every
MAINT (Maintenance circuit pack) error in an EPN. Then, repeat the test.

NOTE:
For a J58890CE, skip to step 2.
1. Procedures for a Global MCC (J58890CH):
a. For a nominal holdover system if there is no AC power at the wall
outlet, have a qualified electrician restore power to the outlet. Power
should range from 170 to 264 VAC.
b. If there is AC power at the wall outlet, then there could be a problem
with the RM0850 rectifiers, BU3200A BIU (battery interface unit), or
battery. Resolve every alarm logged against the POWER MO, and
rerun the test. If the test still fails, the BIU may be defective. Check
the BIU. If the BOD alarm LED is on, replace the BIU.
If the BOD LED is off and the BOK LED is on, then an EPN’s
Maintenance circuit pack may be incorrectly reporting the problem.
Resolve every alarm against these MOs, and rerun the test.
