Replacing Routing Matrix Control Plane Cables
Removing a Control Plane Cable
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-CBs in the TX Matrix Plus router and the TXP-T1600 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).
![]() | Note: If you are replacing a control plane connection in an operational routing matrix, the TX Matrix Plus router and the T1600 router controlled through this connection must have redundant host subsystems. |
To replace a control plane cable:
- Attach an electrostatic discharge (ESD) grounding strap to your bare wrist, and connect the strap to one of the ESD points on the chassis.
- Press the tab on the cable connector installed
in the TXP-CIP port and pull the connector straight out of the port. Ethernet Cable Connector shows the connector.
The control plane ports on the TXP-CIP are labeled LCC0 through LCC3.

Note: The RJ-45 ports labeled LCC4 through LCC7 on a TXP-CIP are reserved for future use.
- Disconnect the cable plugged into the port labeled SFC0 on the corresponding LCC-CB on the T1600 router.

Connecting a Control Plane Cable
To connect a control plane cable:
- Attach an electrostatic discharge (ESD) grounding strap to your bare wrist, and connect the strap to one of the ESD points on the chassis.
- Plug one end of the replacement cable into the appropriate TXP-CIP port.
- Plug the other end of the cable into the port labeled SFC0 on the corresponding LCC-CB on the T1600 router.
- Arrange the cable appropriately.
