Removing a fan
The server comes with five replaceable fans.
To remove any of the five replaceable fans, complete the following steps:
1. Read the safety information that begins on page vii and “Installation guidelines”
on page 57.
2. Turn off the server and all peripheral devices, and disconnect the power cords
and all external cables.
3. Remove the server from the rack and remove the cover (see “Removing the
cover” on page 60).
4. Reconnect the power cord; then, turn on the server.
Attention: Operating the server for extended periods of time (more than 30
minutes) with the cover removed might damage server components.
5. Determine which fan to replace by checking the LEDs on the system board (see
“System-board LEDs” on page 10); a lit LED indicates the fan to replace.
6. Turn off the server; then, disconnect the power cord again.
7. Remove the failed fan from the server:
a. Disconnect the fan cable from the system board (see “System-board internal
connectors” on page 7 for the location of the fan cable connectors on the
system board). Note the routing of the fan cable to the connector; you will
have to route the fan cable the same way when you install the fan.
b. Grasp the top of the fan with your index finger and thumb and lift the fan out
of the server.
