TX Matrix Plus Routing Engine Interface Cable Specifications


For management and service operations, you connect the Routing Engine to an external console or management network through ports on the corresponding TXP-CB.


For troubleshooting only, you can access a T1600 router by connecting a CIP on the router to an external management device. However, you manage the routing matrix through external management devices connected to the TXP-CBs on the TX Matrix Plus router.

The control plane connections between the T1600 routers and the TX Matrix Plus router are provided by UTP Category 5 Ethernet cables between the RJ-45 ports on the TXP-CIPs in the TX Matrix Plus router and the LCC-CBs in the T1600 routers. The maximum length supported is 100 m. The UTP Category 5 cables do not have to be the same length. The cable wiring is straight-through (not crossover).

Table 1 lists the specifications for the cables that connect to management ports.
