Separate the processor from carrier and heat sink
This task has instructions for separating a processor and its carrier from an assembled processor and heat
sink, known as a processor-heat-sink module (PHM). This procedure must be executed by a trained
technician.
About this task
To avoid potential danger, make sure to read and follow the safety information.
Attention: Read "Installation Guidelines" on page 43
sure that you work safely.
Important:
• Do not touch the contacts on the processor contacts. Contaminants on the processor contacts, such as
oil from your skin, can cause connection failures.
• Keep the processor socket clean from any object to prevent possible damages.
• 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.
Note: The heat sink, processor, and processor carrier for the node might look different from those shown in
the illustrations in this section.
Procedure
Step 1. Separate the processor from the heat sink and carrier.
a. Lift the handle to release the processor from the carrier.
b. Hold the processor by its edges; then, lift the processor from the heat sink and carrier.
c. Without putting the processor down, wipe the thermal grease from the top of the processor
with an alcohol cleaning pad; then, place the processor on a static protective surface with the
processor-contact side up.
