Connector and Cable Specifications


This appendix describes the cables that you use to connect the RPS 2300 to other devices. It includes the connector and pinout specifications for these cables:

RPS Cable for the Catalyst 3750-E and 3560-E Switches

RPS Cable for Other Supported Switches

RPS Cable for the Catalyst 3750-E and 3560-E Switches

The RPS cable for the Catalyst 3750-E and 3560-E switches (CAB-RPS-2300-E=) is a 48-inch (1.5-meter) cable with a 22-pin connector on each end. The connectors are keyed for insertion in the correct orientation. Figure B-1 shows the connector, and Table B-1 has the pinout information.

RPS Cable for Other Supported Switches

The RPS cable (CAB-RPS-2300=) used with other supported switches is a 48-inch (1.5-meter) cable with a 22-pin connector on one end and a 14-pin connector on the other end. Figure B-2 and Figure B-3 show the connectors, and Table B-1 has the pinout information.


Note Do not use this cable with a Catalyst 3750-E or 3560-E switch.
