Replacing the Battery Assembly (J58890CH)<br />

The batteries are replaced as an entire assembly.<br />

1. Check the battery voltages at the <strong>test</strong> points on the BIU (Battery Interface Unit).<br />

2. Remove the BIU from the power distribution unit.<br />

3. Disconnect the battery plug from the power distribution unit (J20).<br />

4. Remove the battery assembly from the rear of the cabinet.<br />

5. Install the new battery assembly in the reverse order.<br />

6. Plug the BIU back into the power distribution unit.<br />

Note:<br />

Note: This MO applies to the J58890CE <strong>and</strong> the J58890CH-1 with large battery<br />

holdover.<br />

This MO represents the battery backup unit found in AC-powered multicarrier cabinets.<br />

Because the system does not recognize the type of external power, this MO exists in<br />

DC-powered multicarrier cabinets but serves no functional purpose. In such cabinets, every<br />

POWER <strong>test</strong> should always pass or abort, <strong>and</strong> no POWER alarms should be raised.<br />

Two different types of PN cabinets are supported: multicarrier <strong>and</strong> single-carrier. Both cabinet<br />

types may be powered by either AC or DC external power source. Environmental maintenance<br />

differs according to cabinet type <strong>and</strong> external power supply.<br />

1. UU is the cabinet number indicated in the PORT field from the Alarm or Error Log.<br />

The large batteries are mounted inside a separate battery cabinet <strong>and</strong> can supply holdover<br />

times of 2 to 8 hours depending on the size of the battery. The batteries are circuit breaker<br />

protected <strong>and</strong> are charged by the J58890CH-1. The batteries also contain a thermal sensor that<br />

change the charging voltage depending on the battery temperature.<br />
