Removal and Replacement Procedures— Small Form Factor (SFF) Chassis
2. Install the processor.
Ä
CAUTION:
Before reinstalling a previously used heatsink you must clean the top of the processor and
the bottom of the heatsink with the alcohol pad supplied in the spares kit. After the alcohol has
evaporated, apply thermal grease to the top of the processor using the syringe supplied in the spares kit.
3. Attach the heatsink to the system board-standoff assembly with the four captive screws.
Ä
CAUTION:
Heatsink retaining screws should be tightened in diagonally opposite pairs (as in an X) to
evenly seat the heatsink on the processor. This is especially important as the pins on the socket are very
fragile and any damage to them may require replacing the system board.
4. Reinstall the system board assembly into the chassis and secure it with the long mounting
screw.
Ä
CAUTION:
When reconnecting the cables it is important that they be positioned so they do not interfere
with the sliding of the drive cage or the rotation of the power supply.
