Connection Methods and Cables
Table 2 summarizes the redundancy options and cable requirements for the various external devices that can be supported by
the Cisco RPS.
The connection options are shown in the following figures:
• Quasi-redundant—Figure 6. The AC input to the Cisco RPS is fully redundant, but the DC output to the external devices
is not.
Note Quasi-redundant is the only recommended configuration for Cisco switches and hubs.

1. The cables come in only one length. Custom cable-lengths are not available. Excessive voltage drop and marginal or failed operation can occur with
cables of different lengths. Use of cables other than the ones listed can cause damage to the Cisco RPS or external device.
