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.
