Replacing the Processor
Note: This manual assumes a processor is already installed and you are referring to these steps
to replace your processor. If you are setting up this system for the first time, see the Quick
Start User’s Guide that was included in the product box.
Caution: Use only processors that have been validated to work with this server board. See “Server
System References” on pagexix for a link to the list of compatible processor(s).
Caution: ESD and handling processors: Reduce the risk of electrostatic discharge (ESD) damage to
the processor by doing the following: (1) Touch the metal chassis before touching the
processor or server board. Keep part of your body in contact with the metal chassis to
dissipate the static charge while handling the processor. (2) Avoid moving around
unnecessarily.

2. Power down the server and unplug all peripheral devices and the AC power cable.
3. Remove the server system cover. For instructions, see “Removing the Server
System Cover” on page 14.
