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 4-6 shows the location of the LEDs on the blower module.
