Removing and Replacing the Memory Extender Board
The memory extender board is located directly under the front cover of the chassis. The standard memory

DIMMs.
WARNING Ensure that the server is powered down and all power sources have been
disconnected from the server prior to removing or replacing a memory extender

Voltages are present at various locations within the server whenever an ac power
source is connected. This voltage is present even when the main power switch is in
the off position.
Failure to observe this warning could result in personal injury or damage to
equipment.
CAUTION Observe all ESD safety precautions before attempting this procedure. Failure to follow ESD
safety precautions could result in damage to the server.
