Chapter 1 Overview

Supported Devices and Configurations

Fully Redundant Configuration

The Cisco RPS can provide a fully redundant power source for two of the

supported routers or concentrators. You can use a two-to-one cable (ordered

separately) to connect two external devices to the four DC output power modules,

as shown in Figure 1-2. The two-to-one cable is a Y-shaped cable with two

connectors at one end and one connector at the other end.

In this configuration, the connectors at one end of the Y-shaped cable connect to

two Cisco RPS DC output power modules; the single connector on the other end

of the cable connects to one external device. The power source is fully redundant,

because there are two AC input modules and two DC output power modules

connected to each external device. If any power module fails, there is a full

backup.

Note This configuration is not supported for switches and hubs.
