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:

  1. Attach an electrostatic discharge (ESD) grounding strap to your bare wrist, and connect the strap to one of the ESD points on the chassis.
  2. Press the tab on the cable connector installed in the TXP-CIP port and pull the connector straight out of the port. Figure 1 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.

  3. 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:

  1. Attach an electrostatic discharge (ESD) grounding strap to your bare wrist, and connect the strap to one of the ESD points on the chassis.
  2. Plug one end of the replacement cable into the appropriate TXP-CIP port.
  3. Plug the other end of the cable into the port labeled SFC0 on the corresponding LCC-CB on the T1600 router.
  4. Arrange the cable appropriately.
