Upgrading or replacing controller options In this section Replacing a battery ...19 Replacing the expansion module...20 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 38)" before installing or removing any item that contains a battery pack. IMPORTANT: Whether you are replacing the main cache battery or the secondary (lower) cache battery, remove both batteries so that the board circuitry recognizes the new battery pack. 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. If the main cache battery must be replaced: a. Press the battery retainer tabs down, and push them through to the other side of the cache board (1). Upgrading or replacing controller options 19
