RPS Connector
The 24- and 48-port switches are supported by the Cisco RPS 2300 (model PWR-RPS2300=). The
Catalyst
3560E-12D and 3560E-12SD switches have two power supplies and are not supported by the
RPS-2300.
Warning
Attach only the following Cisco RPS model to the RPS receptacle: RPS 2300.
Statement 370
The RPS 2300 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 3750-E and 3560-E switches (other switch models do not support this management
communication). The RPS
2300 communicates with each switch through the 22-pin cable. All connected
switches can communicate with the RPS
2300 simultaneously. 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
• Report when a switch is powered by the RPS
• Report the RPS power-supply module status
• Read and monitor backup, failure, and exception history
