Chapter 1: Working Inside the System
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 fanassembly as itwas inside thechassis prior to removal,so thatit 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.
3. Remove the foam cover from the front subchassis by pulling it straight out. 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.
