Blower Module

Upper and Lower Cable Management Brackets

The Cisco XR 12416 router includes upper and lower cable management brackets that work together with individual line card cable management brackets to organize interface cables entering and exiting the router (see Figure 1-1).

Network interface cables to the line cards are fed across the brackets, and then through the openings to the individual line card cable management bracket. This system keeps cables out of the way and free of sharp bends.

Caution Excessive bending of interface cables can damage the cables.

Blower Module

The router has two blower modules to distribute air within the chassis. One blower module is located above the upper card cage; the second blower module is located below the lower card cage (see Figure 1-1).
