FIELD ENGINEER/ADMINISTRATOR INSTRUCTIONS:

PROBLEM OVERVIEW: A Sun Fire X4170, X4270 CPU Heatsink needs replacement

WHAT STATE SHOULD THE SYSTEM BE IN TO BE READY TO PERFORM THE RESOLUTION ACTIVITY? :

A data backup is not a pre-requisite but is a wise precaution.
The customer should conduct an orderly software system shutdown.
Then power down the system and disconnect the Power Cord.

- WHAT ACTION DOES THE ENGINEER NEED TO TAKE:
1. Unscrew the two Phillips head screws from the heatsink
Turn the screws alternately one and one half turns until they are fully removed.
2. Twist the heatsink slightly to break the grease seal, lift off the heatsink and
place it upside down on a flat surface to prevent the thermal grease from
contaminating other components.
3. Use an alcohol pad to clean the thermal grease from both the bottom of the
heatsink and the top of the CPU
Be very careful not to get the thermal grease on your fingers as this could result in
contamination of components.
4. Use the syringe (supplied with the new or replacement CPU) to apply
approximately 0.1 ml of thermal grease to the center of the top of the CPU.
Do not distribute the grease.
5. Inspect the heatsink for dust and lint. Clean if necessary.
6. Orient the heatsink so that the two screws line up with the mounting studs
7. Carefully position the heatsink on the CPU, aligning it with the mounting
posts to reduce movement after it makes initial contact with the layer of
thermal grease
Caution ! If the heatsink assembly is moved too much during its installation, the
layer of thermal grease may not be distributed evenly, leading to component damage.
8. Tighten the screws alternately one-half turn until fully seated.
9. Re-fit cover
10. Power on
