Removing Memory Modules
1. Turn off the system, including any attached peripherals, and disconnect the system from the electrical outlet.
2. Open the system. See Opening the System.
NOTICE: Never remove the memory cooling shroud without first powering down the system. Overheating of the system can develop quickly resulting in
a shutdown of the system and the loss of data.
CAUTION: The DIMMs are hot to the touch for some time after the system has been powered down. Allow time for the DIMMs to cool before
handling them. Handle the DIMMs by the card edges and avoid touching the DIMM components.
NOTE: The memory module socket has two alignment keys that allows you to install the memory module in the socket in only one way.
