Cisco PWR675-AC-RPS-N1= Power Supply Unit Battery And Power Supply

The Cisco Redundant Power System 675 (RPS 675) is designed to increase availability in a converged data, voice, and video network. The system
delivers superior internal power supply redundancy and resiliency at an affordable price.
The Cisco RPS 675 supports internal power supply redundancy for one of six Cisco networking devices and provides customers with an immediate
failover capability. The Cisco RPS 675 incorporates a quick failover feature, ensuring customers that the connected device will not reboot in the
event of an internal power supply failure. For example, if an internal power supply fails on one of the six connected devices, the Cisco RPS 675
automatically senses the failure and delivers uninterrupted power to that device.
When a failure is detected, the Cisco RPS 675 sends status information showing that the other connected devices will not be supported until the
failed device is restored or replaced. This status information can be monitored through CiscoWorks 2000 and the Cisco Cluster Management Suite
(CMS) Software that provides Web-based network management. In addition, the Catalyst 3750, 3560, 3550, 2970, and 2950 Series switches send a
trap in the event of an internal power supply failure and the Cisco RPS 675 backing up the failed switch. To achieve one-to-one redundancy, each
device must be connected to a separate Cisco RPS 675.
