Fully Redundant Power
The Cisco RPS can provide a fully redundant power source for up to two Cisco 4000 series routers. You can use a two-to-one cable to connect up to two external devices to the four DC output power modules on the rear panel of the Cisco RPS, as shown in Figure 1-6.The two-to-one cable is a Y-shaped cable with two connectors at one end of the cable and one connector at the other end. Two connectors at one end of the Y-shaped cable connect to two DC output power modules. The other end of the cable connects to one external device. When using two-to-one cables, 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.
