The front cable management system (see
semicircular plastic bobbins mounted on the front of the router below the FPC card cage.
The PIC cables pass between the bobbins and into the tray, keeping the cables organized
and securely in place. The curvature of the bobbins also helps maintain the proper bend
radius for optical PIC cables.
You can pull the front cable management system up and outward to lock it into the
maintenance position. This allows you to access the lower fan tray and the front air filter.

For T4000 routers connected to a TX Matrix Plus router, you can use the optional rear
cable management system (model number CBL-MGR-TXP-3D-LCC) to organize, support,
and provide strain relief for the cables connected to the TXP-LCC-3D SIBs and the cables
connected to the LCC-CBs. The rear cable management system consists of one cable
management arm. The cables are routed to the left side of the T4000 router, and then
toward the top of the chassis, where you can route the cables to the TX Matrix Plus router.
The cable management system adds 9.5 in. (24.1 cm) to the depth of the T4000 chassis,
and 2.4 in. (6.2 cm) to the left side of the chassis.
The LCC rear cable management system can be used for any configuration including,
TXP-T1600 configuration, TXP-T1600-3D configuration, TXP-T4000-3D configuration,
and TXP-Mixed-LCC-3D configuration.
