Chapter 1 Product Overview Power Connectors RPS Connector on the Catalyst 2912 LRE and 2924 LRE XL Switches The RPS is a 300W 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 power supply of a connected device fails and provides the necessary power to the failed device to prevent loss of network traffic. When the device internal power supply has been brought up or replaced, the RPS automatically stops powering the device. Warning Attach only the Cisco RPS (model PWR300-AC-RPS-N1) to the RPS 300 receptacle. Note The RPS can only power one switch at a time. If more than one switch fails at the same time, any subsequent switch is not supported by the RPS until the first switch failure is resolved. For more information on the Cisco RPS 300, refer to the Cisco Redundant Power System 300 Hardware Installation Guide. Console Port You can connect a switch to a PC through the switch console port and by using the supplied rollover cable and DB-9 adapter. You need to provide a RJ-45-to-DB-25 female DTE adapter to connect the switch console port to a terminal. You can order a kit (part number ACS-DSBUASYN=) containing that adapter from Cisco. For console port and adapter pinout information, see the "Connecting to the Console Port" section on page 2-42. 78-6461-04 Catalyst 2900 Series XL Hardware Installation Guide 1-23
