POWER (Battery & Battery Charger) for AC-Powered
Systems
Issue 4 May 2002
10-1345555-233-123
8FAIL
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). Also, this
fault could be generated if the charger is switched off or a battery
is unplugged.
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.
