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.
