Removing a hot-swap fan
The server comes with three 120 mm x 38 mm hot-swap fans in the fan-support
bracket at the front of the server. The following instructions can be used to remove
any hot-swap fan in the server.
Hot-swap fan
To remove a hot-swap fan, complete the following steps:
1. Read the safety information that begins on page vii and “Handling
static-sensitive devices” on page 151.
Attention: Static electricity that is released to internal server components
when the server is powered-on might cause the server to halt, which might
result in the loss of data. To avoid this potential problem, always use an
electrostatic-discharge wrist strap or other grounding system when you work
inside the server with the power on.
2. Unlock and remove the left-side cover (see “Removing the left-side cover” on
page 181).
Attention: To ensure proper system cooling, do not leave the top cover off the
server for more than 2 minutes.
3. Open the fan-locking handle by sliding the orange release latch in the direction
of the arrow.
4. Pull outward on the free end of the handle to remove the fan from the server.
5. If you are instructed to return the hot-swap fan, follow all packaging instructions,
and use any packaging materials for shipping that are supplied to you.
