Battery module

Each controller module assembly includes a removable battery module (for the location, see “Controller module” on page 8). The battery module contains a replaceable Li-Ion battery pack, as shown in the following illustration. The battery pack protects the cache contents if the AC power fails. You can check the amount of battery time available through the Management Interface. The amount of time available is dependent on the amount of cache in the system.

See “Battery module” on page 24 for removal and replacement procedures.
