Hardware Supported

The RPS 675 is compatible with Catalyst switches. For a complete list of the Cisco products that are compatible with the RPS 675, see the Cisco RPS 675 Redundant Power System Compatibility Matrix (not orderable but available on Cisco.com).

Limitations and Restrictions

You should review this section before you begin working with the RPS 675. There is a known limitation that will not be fixed, and there is no workaround. This is the limitation:

The switch might restart when it changes from RPS power to its own internal power. This situation might occur after a power supply on a switch fails, the RPS takes over, and the switch then reverts to its own power. We recommend that you plan for this possibility when restart a switch with its own internal power after using the RPS as backup power.

This problem might occur on any fixed configuration switch except the Catalyst 3750-E and 3560-E switches.

There is no workaround. (CSCdx81023)

Documentation Updates

These updates are for the Cisco RPS 675 Redundant Power System Hardware Installation Guide.

This note was added to the "Product Overview" chapter:


Note The RPS 675 does not support an automatic change over to the internal power supply. You must press the Standby/Active button on the RPS so that the switch again uses the internal power supply.


The Deployment section of the "Cisco RPS 675 Hardware Installation Guide Product Overview" chapter states that when a failure is detected, the Cisco RPS 675 sends status information to network management software stating that the other connected devices are not supported until the failed device is restored or replaced. This is not correct. The RPS does not send traps or system logging messages containing changes in status. However, you can track status by reading the supported MIB objects from the switch to which the RPS 675 is attached. If traps are configured, the connected switches send traps to the network management station.
