Chapter 1 Product Overview Rear Panel Description • List the connected switches and the power-supply module sizes • 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 Cisco RPS 675 The Cisco 675 RPS is a redundant power system that supports six network devices and provides power to one failed switch at a time. It automatically senses when the internal power supply of a connected switch fails and provides power to the failed switch, preventing loss of network traffic. The Cisco RPS 675 has two output levels: -48 V and 12 V. The total maximum output power is 675 W. 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. Note The console port on the Catalyst 2960 8-port switches is on the front panel rather than on the rear panel. Security Slots The Catalyst 2960 8-port switches have security slots on the left and right side panels. You can install an optional cable lock, such as the type that is used to secure a laptop computer, to secure either or both sides of the switch. Figure 1-26 shows the slot on a left-side panel.
