Installing the System Fan Assembly
1. Observe the safety and ESD precautions at the beginning this chapter.
2. Position the fan assembly inside the chassis so that the individual fan cables can easily reach
their connectors on the front panel board.
3. Reconnect the individual fan cables, being careful to match each cable with its correct
connector on the front panel board.
4. Position the fan assembly as it was inside the chassis prior to removal, so that it rests firmly
against the diskette drive at the top and the 5.25-inch bays at the middle and bottom.
5. Reinstall the foam cover. It is molded to match the position of the fans and fits in only one
way.
6. Reinstall the access cover using the original screws.
Removing an Individual System Fan
✏
NOTE
Correct airflow direction: The side of each fan is embossed with
directional arrows indicating airflow direction. Always note the direction of
the arrows on a fan before removing it. You will need this information later
when you install a different fan.
1. Observe the safety and ESD precautions at the beginning this chapter.
2. Remove the access cover (see page 89).
3. Remove the foam cover from the front subchassis by pulling it straight out (see Figure 33 on
page 102). Be careful not to break the foam.
4. For better access to the individual fan cables on the front panel board, carefully rotate the right
edge of the foam fan assembly outward into the opening where the foam cover was.
5. Label and disconnect the desired fan cable from the front panel board. Be sure to note the
position of the cable where it is held in place in the foam fan assembly.
6. Remove the fan cable from the foam assembly, being careful not to break the foam.
7. Remove the fan from the foam assembly. All systems fans sit differently in the assembly, but
in general, each fan can slide in and out of the foam in only one way.
