Remove the heatsink.
To replace the component:
1. Clean the old thermal grease from the processor with the alcohol swab. Allow the alcohol to evaporate
before continuing.
CAUTION: The heatsink thermal interface media is not reusable and must be replaced if the
heatsink is removed from the processor after it has been installed.
2. Remove the thermal interface media protective cover.
CAUTION: To avoid damage to the system board, processor socket, and screws, do not
overtighten the heatsink screws. Use the wrench supplied with the system to reduce the possibility
of overtightening the screws.
CAUTION: To avoid possible thermal damage, install replacement heatsinks as indicated on the
heatsink labels. The heatsinks are not interchangeable between processor 1 and processor 2
within a server blade.
