(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 un its should be showing a r ed 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 unit s 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.
