1 FAIL
NOTE:
For a Global AC MCC (J58890CH) use the procedures
outlined in step 2.
The switch is currently without AC power.
!
WARNING:
Turn off power to the 397C Battery Charger before removing
Fuse F5.
1. Check for AC at the wall outlet.
a. If there is no AC power at the wall outlet, then the problem is
not with the system itself. Power must be restored to the
wall outlet.
b. If there is AC power at the wall outlet, then there could be a
problem with the Battery or Battery chargers. Resolve all
alarms logged against POWER (Battery & Battery Charger),
and rerun the test. If the test still fails, the fuse F5 may have
opened. Replace fuse F5 and rerun the test. If the test still
fails, then the PR-MAINT (Maintenance/Tape Processor) in
a PPN in a system without High or Critical Reliability, the
DUPINT (Duplication Interface) circuit pack in a high or
critical reliability system PPN, or the EPN MAINT
(Maintenance) circuit pack in an EPN multicarrier cabinet
system may be incorrectly reporting the problem.
c. alarms against these MOs, and rerun the test. There are
failures that can occur on the Maintenance/Tape Processor,
Duplication Interface, and EPN Maintenance circuit pack
that are not detected by the respective maintenance, but
that cause many, if not all, environment tests to fail. If many
environment tests are failing, the suspect circuit pack,
depending on the system configuration, should be replaced
and the test rerun.
