2. The charger circuitry mounted underneath the controller top cover has

failed.

3. The BBU charger may stop charging the batteries if the upper

temperature threshold is violated. Check the system event messages

to verify and correct the fault condition.

To replace a BBU module, please follow these steps:

Step 1. Remove the BBU module from the subsystem by loosening its spring

screw, and then gently removing the module from the chassis.

Figure 5-4: Removing the BBU Module

Step 2. Re-install the new BBU. To do this, insert the BBU into the module

slot, and fasten the spring screw to secure the BBU.
