Cisco RPS 2300 Connector

The Catalyst 2960-24PC-L and 2960-24LT-L switches support only the Cisco RPS 2300. This is a redundant power system that can support six network switches and provide power to one or two failed switches at a time. It automatically senses when the power supply of a connected switch fails and provides power to the failed switch, preventing loss of network traffic.

The Cisco RPS 2300 has two output levels: –52 V and 12 V. The total maximum output power depends on the installed power-supply modules.

The six ports on the RPS 2300 provide the power and management communication signals to the Catalyst 2960 switches. The RPS 2300 communicates with the Catalyst 2960-24PC-L and

Catalyst 2960-24LT-L switches through the 22-pin cable (CAB-RPS2300-E=). All other Catalyst 2960 switches connect to the RPS 2300 through a 14-pin connector cable (CAB-RPS2300=).

All connected switches can simultaneously communicate with the RPS 2300. You can configure these RPS 2300 features through the switch software:

•Enable RPS active or standby mode for each connected switch

•Configure switch priority for RPS support

•List the connected switches and their power-supply module size

•Obtain reports when a switch is powered by the RPS

•Obtain status reports for the RPS power-supply module

•Read and monitor backup, failure, and exception history

Console Port

You can connect the switch to a PC by means of the console port and the supplied RJ-45-to-DB-9 female cable. If you want to connect the switch console port to a terminal, you need to provide an RJ-45-to-DB-25 female DTE adapter. You can order a kit (part number ACS-DSBUASYN=) containing that adapter from Cisco. For console port and adapter pinout information, see the “Connector and Cable Specifications” section on page A-1.
