The Cisco RPS provides a quasi-redundant power source for four external devices
that use up to 150W DC each. This configuration is allowed for all supported
devices. You can use a one-to-one cable (one connector at each cable end) to
connect four external devices to the four DC output power modules, as shown in
Figure 1-1. The power source is quasi-redundant because there are two AC input
power modules for the Cisco RPS and one DC output power module for each
external device. The AC input to the Cisco RPS is fully redundant, but the DC
output to the external devices is not.
This is the only recommended configuration for Cisco switches and hubs.
