Installing System Components

Disconnect the fan’s power cable from the system board by depressing the locking tab. See Figure 3-17.

If you are removing the smaller card cage fan (see Figure 3-17):

Pull up on the single release tab that attaches the fan to the chassis.

Slide the fan toward the back panel and lift the fan out.

If you are removing the larger processor cooling fan (see Figure 3-17):

Remove the heat sink and shroud assembly. See "Removing the Processor" on page 62. Do not
remove the processor, however.

Press the release tab that attaches the processor cooling fan to the chassis.

Slide the fan toward the back panel and lift the fan out.
