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.
This configuration is not supported for switches and hubs.
