Communication Manager Maintenance-Object Repair Procedures
1876 Maintenance Procedures for Avaya Communication Manager 3.0, Media Gateways and Servers
8 FAIL 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 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.
!
WARNING:
WARNING: Always turn off the battery charger before replacing the
batteries.
2. Rerun the test. If the test still fails, the PN’s MAINT (Maintenance)
circuit pack could be reporting this condition incorrectly. Resolve
every alarm on this MO, and rerun the test. Some failures on the
PN’s Maintenance circuit pack are not detected by maintenance,
but they cause environment tests to fail. If many environment tests
fail, replace the suspect circuit pack and rerun the test.
3. Procedures for a Global MCC (J58890CH):
a. 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 an over temp condition. If temp is normal,
replace the BIU. If the test still fails, replace the battery in a
small battery system. For a large battery system, escalate the
problem.
Note: The equipment must be installed in a well-ventilated area.
Maximum equipment performance is obtained at an ambient
room temperature between 40 and 120 degrees Fahrenheit (4
and 49 degrees Celsius) for short term operation (not more than
72 consecutive hours or 15 days in a year) and up to 110
degrees Fahrenheit (43 degrees Celsius) for continuous
operation.
c. If the BNA (Battery Not Available) LED is “on,” check the battery
connections including connector J20.
