Heatsink removal and installation

Removing the heatsink

1.
Power down and remove the blade unit from the enclosure (see "Removing the blade unit" on page 36
for details).
2.
Remove the cover of the blade unit (see "Removing/Replacing the blade cover" on page 38).
3.
Loosen the two or four screws (depending on blade type) that secure the heatsink to the mainboard.
4.
Remove the heatsink by gently rotating it back-and-forth sideways with your fingers to release it from the
processor. Set the heatsink aside and upside-down so that nothing comes into contact with the thermal
grease on its underside.

Installing the heatsink

1.
To install the heatsink, apply thermal grease to the top of the processor. (If reinstalling a heatsink, first
clean off the old thermal grease with a clean, lint-free cloth.)
2.
Place the heatsink on the processor then tighten two diagonal screws until snug, then the other two
screws.
3.
When all screws are snug, tighten them all to secure the heatsink to the mainboard.
NOTE: Do not overtighten the screws as this may damage the processor or the heatsink.
4.
Replace the cover on the blade unit and finish by installing the unit back into the blade enclosure.
