therefore, if a fan module is removed from the chassis, the IBM c-type SAN switches and devices
will be shut down to prevent potentially undetectable overheating. However, the switches will be
shut down sooner if the higher-level temperature threshold is exceeded. In normal data center
conditions, if one fan module fails or needs to be removed, the other two fan modules can cool the
system effectively for up to 72 hours.

Installing a Fan Module
About this task
To install a fan module on the IBM c-type SAN Device, follow these steps:
Procedure
1. Hold the fan module so that the Fan Status LED is at the bottom.
2. Place the fan module into the rear chassis cavity so that it rests on the chassis. Gently push the fan
module into the chassis and the guide pin will self-align to the top and bottom chassis matching slots.
After fully engaged, tighten the captive screws to 5 in-lb to secure fan module to chassis. The fan
module will just snap in.
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 outside
surface of the fan module is flush with the outside surface of the chassis.
4. Verify that the Fan Status LED is green. If the LED is not green, one or more fans are faulty. If this
occurs, contact your customer service representative for a replacement part.
Removing a Fan Module
About this task
Warning : When removing the fan module, keep your hands and fingers away from the spinning
fan blades. Let the fan blades completely stop before you remove the fan module.
To remove the fan module from the IBM c-type SAN Device, follow these steps:
Procedure
1. Loosen the four captive screws on the module being removed.
2. Grasp the handles of the fan module with both hands and pull it outward to unseat the power
connector from the backplane.
3. Pull the fan module fully out of the chassis.
Starting Up the Switch
This section provides the following information:
• "Verifying Component Installation" on page 125
• "Powering Up the Switch" on page 125
Warning : Hazardous voltage or energy is present on the backplane when the system is operating.
Use caution when servicing.
CAUTION : During this procedure, wear grounding wrist straps to avoid ESD damage to the switch.
