Chapter4 Replacing Components Replacing a Fan Module
Replacing a Fan ModuleThe fan module is designed to be removed and replaced while the system is operating without presenting
an electrical hazard or damage to the system, if the replacement is performed promptly.
Note The airflow direction must be the same for all power suply and fan modules in the chassis. You can order
all modules with front to back airflow but you can alternatively order back to front airflow.

Removing a Fan Module
Warning
When removing the fan tray, keep your hands and fingers away from the spinning fan blades. Let the
fan blades completely stop before you remove the fan tray.
Statement 258
To remove a fan module, follow these steps:
Step 1 Loosen the captive screws on the fan module by turning them counterclockwise, using a flat-blade or
number 2 Phillips screwdriver if required.
Step 2 Grasp the handle of fan module and pull it outward.
Step 3 Pull the fan module clear of the chassis.
Installing a Fan Module
To install a fan module, follow these steps:
Step 1 Hold the fan module with the LED at the bottom.
Step 2 Place the fan module into the front chassis fan slot so it rests on the chassis, and then push the fan module
into the chassis as far as it can go until the captive screw makes contact with the chassis, and tighten the
captive screw.
Step 3 If the switch is powered on, listen for the fans. You should immediately hear them operating. If you do
not hear them, ensure that the fan module is inserted completely in the chassis and the faceplate of the
module is flush with the outside surface of the chassis.
Step 4 Verify that the fan module LED is green. If the LED is not green, one or more fans are faulty. If this
situation occurs, contact your customer service representative for replacement parts.
