NOTE:
See the illustration below and confirm proper PHM installation by visually checking whether or not
the PHM sits level with the processor socket assembly. The PHM is NOT installed properly if it does not sit
level with the processor socket assembly. Improperly installed PHMs cannot be fastened down. PHMs
can only be fastened down if correctly installed.
