Chapter RPS1000-Business Series 380W RPS Unit Installation & Administration 2 Product Overview The RPS1000 provides N+1 redundancy. The RPS1000 provides seamless failover to internal power supply failures for one of up to six switches. The RPS1000 automatically senses when a connected device has experienced an internal power supply failure. It then begins to supply power to the device. The RPS1000 supplies power until the power supply of the failed device is replaced or the device is replaced. You can then return the RPS1000 to active mode so that it is available to supply power to another device. If a connected device fails, the RPS1000 sends status information to the other connected devices and to network management software. This status information alerts 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 RPS1000. NOTE: The RPS1000 is designed to provide backup for internal power supply failures of connected device power supplies. It is not designed to act as a backup power source that protects against losses of power due to external power outages. We recommend using an uninterruptable power system (UPS) as protection against power outages. The RPS1000 was designed to support specific Linksys Business Series products. Connectors are not interchangeable. Consult your switch documentation to determine if it supports the RPS1000 product. Features The Linksys Business Series RPS1000 is shown in the figure below.
