The Cisco RPS 300 Redundant Power System (PWR300-AC-RPS-N1) provides redundancy for up to six connected devices until one of these devices requires backup power. The RPS 300 automatically senses when a connected device has experienced an internal power supply failure and seamlessly and immediately begins to supply power to the device, providing continuous uptime with no need to reboot. When the RPS is supplying power to a device, it cannot provide power to another device until the failed device's power supply unit is replaced, or the device is replaced, and the RPS is returned to active mode.
If a connected device fails, the RPS 300 sends status information to the other connected devices and to network management software to alert administration that these devices are not supported until the failed device or the power supply of the failed device is brought up or replaced. To achieve one-to-one redundancy, you must connect each device to a different RPS 300.
The Cisco RPS 300 has two output levels: -48 VDC with a maximum output of 144W and 12 VDC with a maximum output of 156W, for a maximum total output power of 300W. The -48V mode powers telephone systems in line-powered switches.
Pulled from a working environment.
This unit is in good physical condition, normal scratches from use (see pictures). Unit powers on and seems to function fine, but due to the nature of the equipment we are unable to fully test it and all observations are for informational purposes only - so it is being offered AS-IS.
