Replacing a battery
WARNING: There is a risk of explosion, fire, or personal injury if the battery pack is not
properly handled. Refer to "Battery replacement notice (on page 35)" before installing or
removing any item that contains a battery pack.
The standard 64-MB cache module does not use a battery. Only the cache upgrade module uses a
battery.
1. Close all applications, and then power down the server. This procedure flushes all data from the
cache.
2. Remove the cache module:
a. Open the ejector latches on each side of the DIMM connector (1).
b. Pull the cache module out of the DIMM slot (2).
3. Press the battery retainer tabs down, and push them through to the other side of the cache board (1).
