Chapter 2 Product Overview
Rear Panel Description
The RPS is a redundant power system that can support six external network
devices and provides power to one failed device at a time. It automatically senses
when the internal power supply of a connected device fails and provides power to
the failed device, preventing loss of network traffic. For more information on the
Cisco RPS 300, refer to the Cisco RPS 300 Redundant Power System Hardware
Installation Guide.
Cisco RPS 675
The Cisco RPS 675 has two output levels: 48V and 12V with a total maximum
output power of 675W. Use the supplied RPS connector cable to connect the RPS
to the switch.
Warning
Attach only the Cisco RPS (model PWR675-AC-RPS-N1=) to the RPS receptacle.

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 B-1.
