Replacing Fan Modules

The five fan modules in the server are numbered as follows when you are facing the front of the server (also see Figure 3-11). The fan numbering as designated by the server’s Cisco IMC software is also listed. For example, FAN 1 is designated as SYS_FAN2 in the software.

Figure 3-10	Fan Module Numbering
FAN 1	FAN 2	FAN 3	FAN 4	FAN 5
SYS_FAN2	SYS_FAN3	SYS_FAN4	SYS_FAN5	SYS_FAN6

To replace or install a fan module, follow these steps:

Caution The fans in the Cisco UCS C22 server are not hot-swappable.

Step 1 Remove a fan module that you are replacing (see Figure 3-11):

a.Power off the server as described in the “Shutting Down and Powering Off the Server” section on page 3-6.

b.Slide the server out the front of the rack far enough so that you can remove the top cover. You might have to detach cables from the rear panel to provide clearance.

Caution If you cannot safely view and access the component, remove the server from the rack.

c.Remove the top cover as described in “Removing and Replacing the Server Top Cover” section on page 3-7.

d.Remove the internal air baffle from the server to provide access to the fan-cable connectors on the motherboard.

e.Disconnect the fan module’s cable from its motherboard connector.

f.Grasp the fan module and lift straight up to free it from the chassis. Carefully free the fan module cable from the fan-tray clips to avoid damaging it.

Step 2 Install a new fan module:

a.Set the new fan module in place, aligning its four rubber pegs with the slots in the fan tray. See Figure 3-11.

b.Connect the fan’s cable to the motherboard connector. Reroute the cable into the cable clips on the fan tray.

c.Replace the air baffle and the top cover.

d.Replace the server in the rack.
