Installation Notes for the Catalyst 3750-X and 3560-X Switch Fan Modules
Published: April, 2010
For information about using the fan module, see the Catalyst 3750-X and 3560-X Switch Hardware Installation Guide. For translations of the safety warnings that appear in this publication, see the Regulatory Compliance and Safety Information for the Catalyst 3750-X and 3560-X Switch.

The switch has two fan modules. Each fan module contains two fans. Fan modules are hot-swappable.

Fan Module Installation
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 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.
Warning Only trained and qualified personnel should be allowed to install, replace, or service this equipment. Statement 1030
Installing a Fan Module
Step 1 Pinch the fan module release handle, and slide the module out.
Caution You should replace the fan module within 5 minutes to avoid overheating the switch.
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.
Warning Do not reach into a vacant slot or chassis while you install or remove a module or a fan. Exposed circuitry could constitute an energy hazard. Statement 206
