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, do the following:

1.Read the safety information that begins on page 5.

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 157).

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.
