Figure 86. PHM location for two-processor configuration
Step 2. Remove the PHM from the system board.
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.
a. Fully loosen the Torx T30 nuts on the PHM in the removal sequence shown on the heat-
sink label.
Note: For reference, the torque required for the screws to be fully tightened/removed is 10+/-
2.0 lbf-in, 1.1+/- 0.2 N-m.
Attention: To prevent damage to components, make sure to follow the indicated tightening/
loosening sequence.
b. Rotate the anti-tilt wire bails inward.
c. Carefully lift the PHM from the processor socket. If the PHM cannot be fully lifted out of the
socket, further loosen the Torx T30 nuts and try lifting the PHM again.
