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 system with High or Critical
Reliability, or the EPN Maintenance circuit pack in an EPN multicarrier cabinet
system for the status of pair of power units in the specified carrier. If both power
units are on and functioning, then the test passes. If both are not on and
functioning, it fails.

(Carrier A) 8
(Carrier B) 16
(Carrier C)
FAIL There is a problem with one or both Power Unit(s) on the recycled
carrier.
1. Since the Power Unit Recycle Test failed, both Power Units in the
recycled carrier should have been powered off by the system
software. Both 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 problem persists, follow normal escalation procedures.
PASS Both power units in the recycled carrier were found to be healthy by
the Maintenance/Tape Processor in a Standard system PPN, the
Duplication Interface circuit pack in a PPN for a system with High or
Critical Reliability, or the EPN Maintenance circuit pack in an EPN
multicarrier cabinet system after the power units were powered down
and back up. If the status LEDs on both 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 power units. Look for and resolve any alarms on these MOs.
