The default failover behavior for the RPS is “first-come, first-served.” Default priorities can be
overridden with a programmable priority, and higher-priority ports can be programmed to
supersede lower-priority ports. This feature gives the network administrator the flexibility to define
the RPS failover policy.
When a failure is detected, the Cisco RPS 2300 sends status information that can be monitored
through Cisco Network Assistant. In addition, Cisco Catalyst 3750-E, 3750, 3560-E, 3560, 3550,
2960, and 2950 Series Switches send a trap in the event of an internal power supply failure,
allowing the Cisco RPS 2300 to back up the failed switch.
PRODUCT APPLICATIONS
The Cisco RPS 2300 can be deployed in a variety of situations to help ensure network resiliency
for mission-critical applications. Figure 3 shows the Cisco RPS 2300 in a converged voice and
data network that includes switches connected to IP phones and PCs. In the event of a switch’s
internal power supply failure, the Cisco RPS 2300 helps ensure voice and data network operation
without interruption. In this scenario, multiple PoE switches are attached to the Cisco RPS 2300.

When designing or upgrading a wiring closet, careful consideration should be given to power
requirements, particularly for PoE deployments. A power architecture can be selected based
on the level of availability desired. The primary power faults to protect against include:
●
Internal power supply failures in network devices
●
Failure of an AC circuit (a circuit breaker tripping, for example)
●
Interruption of utility power
