1. Review the safety precautions listed in “Safety information” on page 107.
2. Turn off the server and peripherals; disconnect cables and cords.
3. Remove the cover. See “Removing the cover” on page 44 for details.
4. Determine which fan to replace by checking the LED at each fan; a lit LED
indicates the fan to replace. See “Identifying problems using status LEDs” on
page 13.
Note: The fan LEDs are illuminated by the light path diagnostic circuit, and will
remain lit for up to 12 hours after the AC power has been removed from
the server.
5. Remove the fan from the server:
a. Disconnect the fan cable from the system board.
b. Lift the fan away from the server.
6. Install the replacement fan:
a. Orientate the fan so that the air flow arrow on the side of the fan is facing or
pointing toward the rear of the server.
Note: Proper air flow is from the front to the rear of the server.
b. Push the replacement fan assembly into the server until it clicks into place.
c. Connect the fan cable to the system board.
d. If the FAN LED is lit, reseat the fan.
7. Install the cover (see “Installing the cover” on page 61).
8. Start up the system, the system error light will either remain on or turn off. If the
system error light remains on you will have to turn off the server to perform
further troubleshooting.
