Removing and Replacing a Hot-Swappable Chassis Fan Unit

Removing and Replacing a Hot-Swappable Chassis Fan Unit
There are three interchangeable, hot-swappable chassis fan units in the server. Fan unit 1 is located behind
the memory carrier assembly. Fan units 2 and 3 are located in the center of the chassis between the disk
drives and the I/O board assembly. There are also three external hot-swappable fans located at the rear of the
chassis. You can replace the hot-swappable fans using the procedures in this section when system power is on
or off.
CAUTION Observe all ESD safety precautions before removing or replacing a fan unit. Failure to follow
ESD safety precautions can result in damage to the server.
NOTE A hot-swappable device does not require interaction with the operating system before the
device is removed from or installed into the server.
The dc power to the server does not have to be off to remove or replace a hot-swappable chassis
fan unit.

Removing an Internal Hot-Swappable Chassis Fan Unit

To remove an internal hot-swappable chassis fan unit, follow these steps:
Step 1. If rack installed, slide the server completely out from the rack. See "Extending the Server from the
Rack" on page 57.
Step 2. Remove the top cover. See "Removing the Top Cover" on page 58.
Step 3. Insert thumb and forefinger into the openings on the top of the fan and squeeze until the fan
releases from the socket.
Step 4. Pull the fan straight up and out of the chassis.
CAUTION

To prevent server components from overheating, replace the fan within 20 seconds.
Failure to observe this caution results in the server automatically shutting down to
prevent an overtemperature condition.
