• On a two processor system, if you remove a processor for replacement do not
attempt to operate the system with a single processor as the server might
overheat due to improper airflow. A two processor system requires both
processors and their heatsinks installed to operate properly.
1. Prepare the server for service.
a. Power off the server.
See Powering Down the Server.
b. Disconnect the power cords from the power supplies.
See Disconnect Cables From the Server.
c. Extend the server to the maintenance position.
See Extend the Server to the Maintenance Position.
d. Attach an antistatic wrist strap to your wrist, and then to a metal area on the
chassis.
See Take Antistatic Measures.
e. Remove the server top cover.
See Remove the Server Top Cover.
f. Remove the air baffle.

2. Identify the location of the failed processor by pressing the Fault Remind button on
the motherboard.
