Installing 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 install any hot-swap fan in the server.

Hot-swap fan

To install 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.Touch the static-protective package that contains the hot-swap fan to any unpainted metal surface on the server; then, remove the fan from the package.

3.Open the fan-locking handle on the replacement fan.

4.Insert the fan into the socket and close the handle to the locked position.

5.Install and lock the left-side cover (see “Installing the left-side cover” on page 158).

Removing a microprocessor and heat sink

To remove a microprocessor, complete the following steps:

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

2.Turn off the server and peripheral devices, and disconnect the power cords and all external cables.

3.Carefully turn the server on its side so that it is lying flat, with the cover facing up.

Attention: Do not allow the server to fall over.

4.Unlock and remove the left-side cover (see “Removing the left-side cover” on page 157).
