ooling Fan in Upper Power Supply Bay
Figure 4-12. Removing Fan in the Upper Power Supply Bay
1. Remove both computer covers.
See “Computer Covers” found earlier in this chapter.
2. Disconnect the cooling fan’s power cable from the fan connector on the
system board and feed the cable through the hole in the top of the
power supply bay.
3. Remove the screw on the left side of the chassis that holds the metal fan
carrier.
WARNING: Only trained service technicians should perform this proce-
dure. Do not remove the left computer cover with the power on unless
you are replacing a cooling fan. (Never remove the right computer cover
with the computer power on. There are high voltages in this area that can
cause bodily harm.) Also, do not touch or attempt to service any compo-
nents other than the cooling fan using this procedure.
CAUTION: See “Precautionary Measures” at the beginning of this
chapter.
