Removing and Replacing the Fan Assembly Module

The fan assembly module does not need to be replaced when it is operating normally. If a failure LED comes on, use the following procedure to remove and reinsert the fan assembly module to test the connection. If the failure LED is still on after removing and reinserting the module, use the following procedure to replace the fan assembly module.

•Single Fan Failure—This yellow LED indicates that one of the four fans in the module has failed. The module can still provide enough cooling to safely operate the Cisco uBR10012 universal broadband router chassis, but it might begin operating the fans in its high-speed mode to do so. If this LED comes on, replace the fan assembly module as soon as is conveniently possible.

•Multiple Fan Failure—This yellow LED indicates that two or more fans in the module have failed, and that the module is no longer able to consistently cool the Cisco uBR10012 universal broadband router chassis. To prevent overheating the chassis and possible damage to the line cards and other modules, replace the fan assembly module immediately.

The fan assembly module supports hot-swapping and can be replaced without interrupting system operation.

Caution Do not run the Cisco uBR10012 universal broadband router chassis without a working fan assembly module for more than three minutes. To prevent the possibility of the system overheating, be sure that the replacement fan assembly module is out of its box and packaging, so it is ready to install as soon as the defective module is removed.

Unpack the Fan Assembly Module

To unpack the fan assembly module, complete the following steps:

Step 1 Open the shipping carton by cutting the packing tape along the flaps on the top of the box.

Step 2 Lift off the top layer of packaging to expose the module.

Step 3 Remove the fan assembly module from the box.

Step 4 Keep the packaging and the carton to return the defective unit to the factory. See the “Obtaining Technical Assistance” section on page 16 for more information.
