Replacing the memory cache DIMM
Attention: To avoid damage to the DIMM, you must first remove the memory cache battery and wait
the required time period before you install or remove the DIMM. Follow the instructions in this
procedure exactly.
Attention: To avoid overheating the storage enclosure and causing damage to its components, replace
failed parts within 10 minutes. The Recovery Guru in the Storage Manager software identifies failed
parts.
Do not remove the failed part from the storage enclosure until you:
v Review the replacement procedure for the failed part in this guide.
v Locate screw drivers or any other hand tools that you might need to replace the failed part.
v Receive the replacement part and are ready to install it in the enclosure.
Use these procedures if you are replacing a failed DIMM or if you are removing and installing the DIMM
as directed in “Replacing a controller” on page 91.
