CAUTION:
The power-control button on the device and the power switch on the power supply do not turn off the
electrical current supplied to the device. The device also might have more than one power cord. To
remove all electrical current from the device, ensure that all power cords are disconnected from the
power source.

Hot surface nearby.
About this task
Attention:
• Read "Installation Guidelines" on page 47
work safely.
• Power off the server and peripheral devices and disconnect the power cords and all external cables. See
"Power off the server" on page
• Prevent exposure to static electricity, which might lead to system halt and loss of data, by keeping static-
sensitive components in their static-protective packages until installation, and handling these devices with
an electrostatic-discharge wrist strap or other grounding system.
• Do not allow the thermal grease on the processor or heat sink to come in contact with anything. Contact
with any surface can compromise the thermal grease, rendering it ineffective. Thermal grease can damage
components, such as the electrical connectors in the processor socket.
Procedure
Step 1. Make preparation for this task.
a. If there is any old thermal grease on the processor, gently clean the top of the processor using
an alcohol cleaning pad. Dispose of the cleaning pad after all of the thermal grease is removed.
Note: Make sure the alcohol has fully evaporated before applying new thermal grease.
b. To ensure the best performance, check the manufacturing date on the new heat sink and make
sure it does not exceed 2 years. Otherwise, wipe off the existing thermal grease from the new
heat sink, and apply new grease on the top of the processor for optimal thermal performance.
c. Apply the thermal grease on the top of the processor with syringe by forming four uniformly
spaced dots, while each dot consists of about 0.1 ml of thermal grease.
