Removal and Replacement Procedures
•
Handle the processor and heat sink with care. Damage to either may affect processor
performance.
•
The pins beneath the processor are very fragile. Do not bend or damage them.
•
Always use a new heat sink when replacing processors. Failure to use new components
can cause damage to the processor.
•
Be sure that the server has the most recent ROM version. Failure to flash the ROM before
installing processors can cause system failure.
•
To prevent the heat sink from tilting to one side during installation/removal procedures,
observe a diagonally opposite pattern (an "X" pattern) when loosening and tightening the
four spring-loaded screws.
To remove a processor:
1. Perform the pre-installation procedures described on page 2-5.
2. If necessary, remove any accessory boards or cables that prevent access to the air duct.
3. Lift the air duct away from the processor sockets.
Keep it for reinstallation later.
Figure 2-33: Removing the air duct
4. Locate the processor you want to remove.
