Battery and Power Supply Query Test (#5)
8 FAIL DC-powered cabinet: The PN’s Maintenance circuit pack is
incorrectly reporting a problem with power. Replace the suspect circuit
pack and run the test again.
AC-powered cabinet: 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: 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.
