1. Power off the server as described in “Powering Off the Server” on page 28 .
2. If the server is in a rack, slide it far enough from the rack so that you can
remove the main cover. If you cannot safely view and access the component,
remove the server from the rack.
3. Remove the top cover as described in “Removing the Top Cover” on page 33 .
4. Identify which CPU and heatsink you are replacing.

fault LED on the motherboard for each CPU (see
