Troubleshooting the Cooling Subsystem
The Cisco XR 12406 router has a blower module located on the rear of the
chassis, which provides cooling air for the router components. The blower module
receives power and signals though a connector recessed in the blower module.
This connector mates with a connector mounted on the PDU. The blower module
contains three fans, one connector, and one controller card.
Figure 4-7 shows the location of the LEDs on the blower module.
