3-30 Sun Fire X4100/X4100 M2 and X4200/X4200 M2 Servers Service Manual • August 2009
Note – System cooling might be affected by dust and contaminant build-up.
Therefore, you should open and check systems approximately every six months (or
more often in dirty operating environments). Check system heatsinks, fans, and air
openings. If necessary, clean systems by carefully brushing, blowing, or vacuuming
contaminants from the system.
13. Install the heatsink.
a. Turn the heatsink upright and reinsert the four springs and mounting bolts.
Caution – Avoid moving the heatsink after it has contacted the top of the CPU. Too
much movement could disturb the layer of thermal grease, leading to component
damage.
b. Carefully position and align the heatsink over the CPU.
Note – The heatsink is not symmetrical and it must be aligned before you place it on
the CPU. Note that the half of the Sun Microsystems logo imprinted on the top of the
heatsink will create a complete logo when correctly aligned with the adjacent
heatsink. See FIGURE 3-17 on page 26.
c. Lower the heatsink onto the CPU, aligning the mounting screws with their
holes on the motherboard.
d. Using an adjustable torque driver, alternately tighten the two heatsink
mounting screws 180 degrees at a time until each spring is completely
compressed. Tighten screws to 7 in-lbs (0.8 Nm).
3.12.4 Replacing the DVD-ROM Drive
Note – If you are installing a DVD-ROM upgrade kit to a system that previously did
not have a DVD-ROM drive, see Section 3.12.5 on page 3-33.
Note – This component is an FRU and should be replaced only by qualified service
technicians. Contact your Sun Service representative for assistance.
