Chapter 5 Maintaining the Router

Removing and Replacing the Blower Module

Troubleshooting the Blower Module Installation

Use the following procedure to troubleshoot the blower module if it is not operating properly after installation.

Step 1 Be sure the router is powered on and that all power cords are connected properly. Step 2 Loosen the captive screws and reseat the blower module to the chassis.

Retighten the captive screws to ensure the blower module is properly seated to the backplane connector.

Step 3 Check the blower module status indicators:

OK (green)—Indicates that the blower module is operating normally. This indicator should light as soon as the blower module is installed and receives power from the backplane connector.

If this indicator remains on, and the blower module fans fail to operate after several attempts to reseat the blower module, replace it with a spare.

If the spare blower module also fails, power off the router and contact a Cisco service representative for assistance.

Fail (red)—This indicator remains off during normal operation. If this indicator is on, the system has detected a fan failure or other fault in the blower module.

If this indicator remains on, and the blower module fans fail to operate after several attempts to reseat the blower module, replace it with a spare.

If the spare blower module also fails, power off the router and contact a Cisco service representative for assistance.
