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.
