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
52
)" 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).
