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.

3. Procedures for a Global MCC (J58890CH):
a. Look to see if any “red” LEDs are “on” on any of the rectifier modules or
the BIU (Battery Interface Unit) located in the Power Distribution Unit
(J58890CH).
b. If the BTW (Battery Temp Warning) LED on the BIU is “on” check the
batteries for a over temp condition
(a)
if temp is normal
(a)
replace the
BIU, If the test still fails replace the battery in a small battery system.
For a large battery system escalate the problem.
c. If the BIF (Battery Interface Unit) LED is “on” replace the battery
interface unit.
d. If the BNA (Battery Not Available) LED is “on” check the battery
connections including connector J20.
