Removing and Replacing Hot-Swap Chassis Fans

There are three hot-swap chassis fan units in the HP server. Fan units 0, 1, and 2 are in the center of the chassis, spanning the full chassis width. Fan units 0 and 1 are interchangeable and are in the left and center positions. Fan unit 2 is smaller and only fits into the right-most position (behind the power supply).

CAUTION	Observe all ESD safety precautions before attempting this procedure. Failure to follow ESD
	safety precautions could result in damage to the server.
CAUTION	When the server is running, the top cover must be replaced within two minutes to prevent
	components from overheating. If the top metal cover is not replaced within five minutes, the
	server automatically shuts down.
NOTE	A hot-swap device does not require interaction with the operating system before the device is
	removed from or installed into the server.
	The ac power to the server does not have to be off to remove or replace a hot-swap chassis fan.

Removing a Hot-Swap Chassis Fan Unit

To remove a hot-swap chassis fan unit, follow these steps:

Step	1.	If rack mounted, slide the HP server out from the rack until it stops. See “Extending the Server
		from the Rack” on page 39.
Step	2.	Remove the top cover. See “Removing the Top Cover” on page 43.
