Chapter 6 Maintaining the Router

Removing and Replacing AC and DC Power Subsystem Components

Step 3 Check the blower module status indicators:

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

•Fail (red)—This indicator remains off during normal operation. If the 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 normally after several attempts to reseat the blower module, replace the existing blower module with a spare.

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

Removing and Replacing AC and DC Power Subsystem Components

This section contains removal and replacement procedures for the AC and DC power systems used with the Cisco 12006 and Cisco 12406 series routers. If you ordered an upgrade kit, you can use these same procedures to upgrade all of the power system components.

The illustrations in this procedure represent both original and upgraded power supplies and PDUs shipping with the Cisco 12006 and Cisco 12406 series routers. Depending on your system, these components may not look exactly like those in your chassis, but the removal and replacement procedures are essentially the same. Multiple illustrations are presented to represent original and new models where appropriate.
