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 router 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.
NOTE:
The PTX5000 supports two midplanes. First supported in Junos 14.1,
the PTX5000BASE2 model is a chassis with an enhanced midplane that
requires high-capacity PDUs and PSMs. The enhanced midplane is identified
as
Midplane-8SeP
operational-mode CLI command.
If you are installing FPC3-PTX-U3, it must be installed in the PTX5000BASE2
model.

The front cable management system for the PTX5000 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 PTX5000. The front cable management system adds 3.8 in. (9.7
cm) to the depth of the chassis.
You can install a rear cable management system with the High Capacity DC power supply.
The rear cable management system adds 5.5 in. (14 cm) to the depth of the chassis. See
"Installing the PTX5000 Cable Management System for High Capacity DC PDU" on
page 196
for details.
NOTE:
We recommend that you use the cable management system to
maintain the cable bend radius.
