Description / Recommendation

There is a reserve power fault. A problem exists with the battery charger or,

less likely, the batteries. Also, this fault could be generated if the charger is

switched off or a battery is unplugged.

1. Replace the battery charger and the battery. The fault should disappear.

2. Rerun the test. If the test still fails, then the PN's MAINT (Maintenance)

3. Procedures for a Global MCC (J58890CH):

More information continues.

For a Global AC MCC (J58890CH) use the procedures outlined in step

Always turn off the battery charger before replacing the

circuit pack could be reporting this condition incorrectly. Resolve every

alarm on this MO, and rerun the test. There are failures that can occur on

the PN's Maintenance circuit pack that will not be detected by their

respective maintenance, but which will cause many, if not every,

environment test to fail. If many environment tests are failing, the suspect

circuit pack, depending on the system configuration, should be replaced

and the test rerun.

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

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 BNA (Battery Not Available) LED is "on" check the battery

connections including connector J20.
