Replacing a 1 (RU) Fan Module
a) Loosen the captive screws on the fan tray by turning them counterclockwise, using a flat-blade or number 1 Phillips
screwdriver if required.
b) Grasp the captive screws of the fan tray and pull it outward.
c) Pull the fan tray clear of the chassis and set it on an antistatic surface or repack it in packing materials.
Step 2
Install the replacement fan tray as follows:
a) Hold the fan tray with the sheet metal flange holding the connector on the bottom.
b) Place the fan tray into the front chassis cavity so it rests on the chassis, and then push the fan tray into the chassis as
far as it can go until the captive screw makes contact with the chassis.
c) Tighten the captive screw.
d) Listen for the fans if the device is powered on. You should immediately hear them operating. If you do not hear them,
ensure that the fan tray is inserted completely in the chassis and the faceplate is flush with the outside surface of the
chassis.
e) Verify that the LED is green. If the LED is not green, one or more fans are faulty. If this problem occurs, contact
your customer service representative for a replacement part.

module.
The fans might still be turning when you remove the fan assembly from the chassis. Keep fingers,
