To replace a fan tray, follow these steps:
Step 1 Remove a fan tray:
a. Power off the server as described in the “Shutting Down and Powering Off the Server” section on 
page 3-7.
b. Disconnect all power cords from the power supplies.
c. 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.
d. Remove the top cover as described in the “Removing and Replacing the Server Top Cover” section 
on page 3-9.
e. Remove the cable cover that sits over the fan tray and set it aside.
Note If your server has an optional LSI battery-backup unit (BBU) mounted to the fan tray, you must 
remove the BBU. Remove the three screws that secure the BBU to the bracket on the fan tray 
and set the BBU aside. See the 
“Replacing an LSI MegaRAID Battery Backup Unit” section on 
page 3-41 for more information.
f. Remove the three screws that hold the battery unit bracket to the fan tray and then remove the battery 
unit bracket to provide clearance to the cable harness (see 
Figure 3-15).
g. Remove the cable harness from the fan tray connector.
h. Remove the two screws that secure the fan tray to the chassis posts and lift the tray out of the chassis.
Step 2 Install a fan tray:
a. Place the new fan tray into the chassis, aligning the two bracket holes on the fan tray with the chassis 
posts.
b. Replace the two screws that secure the tray to the chassis posts.
c. Replace the cable harness to fan tray connector.
d. Replace the battery unit bracket and the three screws that secure it to the fan tray.
Note If you removed an optional LSI BBU from the fan tray, replace it and the three screws that secure 
it to the fan tray.
e. Replace the cable cover and the top cover.
f. Replace the server in the rack, replace power cords and any other cables, and then power on the 
server by pressing the Power button.
