About this task
The replacement procedure is identical for all types of processors on all daughter cards, except the KPDC.
Procedure
1. Remove the blade from the cabinet.
2. Remove the T15 Torx screws that attach the shroud to the blade and remove the shroud.
3. Remove the T10 Torx screws that attach the air diffuser bracket to the blade and remove the bracket.
4. Disconnect the power cable connectors (press the release tab and pull cable straight out) and remove the
power cable assembly.
5. Locate the defective processor and remove the processor air duct covering it.
6. Loosen the captive T15 Torx bolts (4) that attach the processor heat sink to the blade in an alternate criss-
cross pattern until they are completely loose.
7. Remove the heat sink and retain it for installation on the replacement processor. If removing more than one
processor, note the position of each processor heat sink so each heat sink is returned to its original position.
8. Remove the thermal grease from the processor with a dry, clean cloth.
Do not use a liquid, such as isopropyl alcohol. Ensure that the grease does not get under the socket cover.
9. Open the lever near the unlocked symbol and rotate the lever up 100 degrees.
