Power Unit Query Test (#127)
This test queries the Maintenance/Tape Processor in a Standard system PPN, the
Duplication Interface circuit pack in a PPN for a High or Critical Reliability
system, or the EPN Maintenance circuit pack in an EPN multicarrier cabinet
system for the status of the pair of port carrier power units in the specified carrier.
If both port carrier units are on and functioning, the test passes. If both are not on
and functioning, the test fails.

FAIL There is a problem with one or both port carrier power units on the
recycled carrier.
1. Since the Power Unit Recycle Test failed, both port carrier power
supplies in the recycled carrier should have been powered off by
the system software. Both port carrier power units should be
showing a red status LED, instead of a green one. Since the Power
Unit Query Test is a subset of the Power Unit Recycle Test, the
Power Unit Query Test (#127) should also fail. Run the Power Unit
Query Test by using the test environment P command where P is
the appropriate port network number.
2. If the test fails, follow the repair procedures described for Test
#127. If the problem persists, follow normal escalation procedures.
PASS Both port carrier power units in the recycled carrier were found to be
healthy by the Maintenance/Tape Processor in Standard system PPN,
the Duplication Interface circuit pack in a PPN for a High or Critical
Reliability system, or the EPN Maintenance circuit pack in an EPN
multicarrier cabinet system after the port carrier power units were
powered-down and powered up again. If the status LEDs on both port
carrier power units are not showing green, then the PR-MAINT
(Maintenance/Tape Processor), DUPINT (Duplication Interface) circuit
pack, or the EPN MAINT (Maintenance) circuit pack may have
incorrectly reported the state of the port carrier power units. Look for
and resolve any alarms on these MOs.
