Installation Guidelines
Observe these guidelines when removing or installing a fan module:
• Do not force the fan module into the slot. This can damage the pins on the switch if they are not aligned
with the module.
• A fan module that is only partially connected to the switch can disrupt the system operation.
• The switch supports hot swapping of the fan module. You can remove and replace the module without
interrupting normal switch operation.
Only trained and qualified personnel should be allowed to install, replace, or service this equipment. Statement

Warning
Installing a Fan Module
Procedure
Step 1 Pinch the fan module release handle, and slide the module out.
You should replace the fan module within 5 minutes to avoid overheating the switch.
Caution
Step 2 Install the fan module in the fan slot, and firmly push it into the slot, applying pressure to the end of the
module, not the extraction handles. When correctly inserted, the fan module is flush with the switch rear panel.
When the fan is operating, a green LED is on in the top left corner of the fan.
Do not reach into a vacant slot when installing or removing a module. Exposed circuitry is an
energy hazard. Statement 206
