Understanding the Cable Management System, Cables, and Connectors
Purpose Inspect the router cables in the cable management system to ensure that fiber-optic
cables have the proper bend radius and that all cables are organized and securely in
place.
Inspect the PIC cables and connectors to ensure that they transport incoming
packets from the network and transmit outgoing packets to the network.
Inspect the power cables and connectors to ensure that power is supplied to the
router.
Inspect the Routing Engine external cables and connectors to ensure that you can
connect external devices to the router.
What Is the Cable
Management System
All Juniper Networks routers have a method of cable management. Although you
are not required to use the cable management system, we recommend that you do
so. The cable management system maintains the proper bend radius for fiber-optic
PIC cables. It keeps installed cables organized, securely in place, and tangle free.
The following sections describe the location of the cable management system on
each routing platform.
