Installing System Components 113
Removing Memory Modules WARNING: Only trained service technicians are authorized to remove the system
cover and access any of the components inside the system. Before you begin this
procedure, review the safety instructions that came with the system.
WARNING: The memory modules are hot to the touch for some time after the
system has been powered down. Allow time for the memory modules to cool
before handling them. Handle the memory modules by the card edges and avoid
touching the components on the memory module.
CAUTION: To ensure proper system cooling, memory-module blanks must be
installed in any memory socket that is not occupied. Install a memory-module
blank if you are removing a memory module and do not intend to install a
replacement.
