Note:
Note: This MO applies to the J58890CE and the J58890CH-1 with large battery
holdover.
This MO represents the battery backup unit found in AC-powered multicarrier cabinets.
Because the system does not recognize the type of external power, this MO exists in
DC-powered multicarrier cabinets but serves no functional purpose. In such cabinets, every
POWER test should always pass or abort, and no POWER alarms should be raised.
Two different types of PN cabinets are supported: multicarrier and single-carrier. Both cabinet
types may be powered by either AC or DC external power source. Environmental maintenance
differs according to cabinet type and external power supply.

1. UU is the cabinet number indicated in the PORT field from the Alarm or Error Log.
The large batteries are mounted inside a separate battery cabinet and can supply holdover
times of 2 to 8 hours depending on the size of the battery. The batteries are circuit breaker
protected and are charged by the J58890CH-1. The batteries also contain a thermal sensor that
change the charging voltage depending on the battery temperature.
