NOTE
A general rule about the correct airflow direction: the removable fan
pulls air from in front of the chassis so that it flows across the boards and out
the back. Thus, the fan must be oriented for the correct airflow direction. If
you place the fan so the label faces the back of the chassis, this should
provide the correct orientation. You can confirm this by checking the
embossed arrows on the side of the fan as you place it in its bracket:
⇒
Arrow points horizontally toward back of chassis
⇑
Arrow points vertically up
Replace a failed fan with the same type as the one removed, with a
tachometer signal, or an approved fan. For a list of approved fans, contact
your customer service representative.
1. Position the cable side of the fan, with the label side facing the card guide. Line up
the screw holes and insert the four mounting screws. Take care not to pinch the fan
cable when mounting the fan.
2. Replace the bezel.
3. Reconnect the fan power cable connector on the server board.
4. Reinstall the add-in boards, each in the slot it was removed from.
5. Reconnect to the add-in boards any cables you removed.
6. Reinstall the side and front covers,

from the chassis. Save the screw to use later.
4. On the front panel board, remove and save the screw from the threaded standoff to
use later.
5. Grasp the front panel board, and carefully pull it toward the back of the system until it
pops off the snap-on standoff.
6. Disconnect the front panel board signal cable from the server board.
7. Remove the front panel board from the system, and place it on an antistatic foam pad
or a grounded workstation.
