Installing Fans for High-Power Drives
If you plan to use SCSI drives whose power exceeds 15 watts, you must install three additional
system fans: two in the front fan assembly and one in the upper power supply bay. To perform
this task, you must purchase a kit.
1. Remove four screws, the grill plate, and fan from your kit.
2. Remove the plate (A in Figure 35) that covers the power supply bay closest to the PCI slots. It
is the uppermost bay when the server is standing upright in pedestal mode.
3. Using four screws, attach the fan to the grill plate (E and F in Figure 35) so that the fan’s label
faces the plate.
4. Insert the fan/grill plate assembly into the power supply bay so that the cable points downward
(D in Figure 35) from the fan toward the other two power supplies, and so the fan’s label faces
out the back of the chassis. This alignment is important to ensure correct airflow direction.
