Removing memory modules
Prerequisites
1. Remove the cooling shroud.
NOTE:
The memory modules are hot to touch for some time after the system has been powered down. Allow the memory
modules to cool before handling them. Handle the memory modules by the card edges and avoid touching the components
or metallic contacts on the memory module.
CAUTION: To ensure proper system cooling, memory module blanks must be installed in any memory socket that
is not occupied. Remove memory module blanks only if you intend to install memory modules in those sockets.
