NOTE:
For a Global AC MCC (J58890CH) use the
procedures outlined in step 3.
There is a reserve power fault. A problem exists with the
battery charger (more probable) or the battery (less
probable).
1. Replace the battery charger or the battery. The fault
should disappear. However, the test fails with Error
Code 4 if the battery is charging.
!
WARNING:
Always turn off the battery charger before
replacing the batteries.
2. Rerun the test. If the test still fails with an error code
other than 4 (that is, there is something wrong
besides the battery needing charging), the
PR-MAINT (Maintenance/Tape Processor) in a
multicarrier cabinet PPN system without High or
Critical Reliability, the DUPINT (Duplication
Interface) circuit pack in a PPN for a High or Critical
Reliability, or the EPN MAINT (Maintenance) circuit
pack in an EPN could be reporting this condition
incorrectly. Resolve all alarms on 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 be 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. If the test still fails, then follow normal
escalation procedures.
