the midplane from the rear of the chassis. The cooling system components also connect
to the midplane.
The midplane performs the following major functions:
Data path—Data packets are transferred across the midplane from the Packet
Forwarding Engine on the originating FPC to the SIBs, and from the SIBs across the
midplane to the Packet Forwarding Engine on the destination FPC.
Power distribution—The power distribution units are connected to the midplane, which
distributes power to all the packet transport switch components.
Signal path—The midplane provides the signal path to the FPCs, SIBs, Routing Engines,
control boards, and other system components for monitoring and control of the system.

The cable management system for the PTX5000 Packet Transport Switch consists of
channels above the FPCs. The cable management system organizes, supports, and
provides strain relief for the PIC cables . The PIC cables are routed toward the top into
the cable management system, keeping the cables organized and securely in place. All
the cables from one FPC are routed to one channel. The cables are routed from the cable
management system to the left side of the packet transport switch. The cable
management system adds 3.8 in. (9.7 cm) to the depth of the chassis.
NOTE:
We recommend that you use the cable management system to
maintain the cable bend radius.
