Figure 96. Removing a PHM
Fully loosen the Torx T30 nuts on the PHM
in the removal sequence shown
on the heat-sink
label.
Rotate the anti-tilt wire bails inward.
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.
Notes:
• Do not touch the contacts on the bottom of the processor.
• Keep the processor socket clean from any object to prevent possible damages.
After you finish
• Each processor socket must always contain a cover or a PHM. Protect empty processor sockets with a
cover or install a new PHM.
• If you are removing the PHM as part of a system board replacement, set the PHM aside.
• If you are reusing the processor or heat sink, separate the processor from its retainer. See “Separate the
processor from carrier and heat sink” on page 183
• If you are instructed to return the defective component, please package the part to prevent any shipping
damage. Reuse the packaging the new part arrived in and follow all packaging instructions.
