CHAPTER 4: Installing Components

Replacing system fans

This server contains five system fan groups seated in the fan cage. The fan cage is located inside the chassis and can hold as many as five groups of hot-swappable fans. When replacing a fan, it is not necessary to power off the server. These fans maintain the ideal temperature for the system board, backplane and disk drives. If one fan group fails, the speed of the other fan groups will increase. With the bad one replaced, the other fan groups may revert to the normal speed.

To replace a system fan:

1Follow the instructions in “Preventing static electricity discharge” on page 24.

2Follow the instructions in “Opening the server case” on page 25.

3Determine which fan group needs to be replaced by noting which fans are not operating.

4Pull up the locking handle (1) on the system fan, then lift the fan group (2) from the fan cage in the chassis.

5Insert the replacement fan group into the fan cage and press down the locking handle to secure the fan group in place.

Important

Make sure that the arrows on top of the fans indicating airflow point to the back of the chassis. The fan cable should exit the fan module toward the back of the chassis.

6Replace the fan duct by placing it in the chassis.

7 Follow the instructions in “Closing the server case” on page 27.
