Most data centers require power source redundancy to ensure that their mission-critical network devices are always running. Newer devices usually include a secondary power outlet. But redundancy is also important for legacy devices with just one power input.
The Fallback Power Switch is designed to provide a reliable and safe power fallback for these single-corded legacy devices. The switch includes dual AC power inlets for connections to both primary and secondary power source. If the primary source fails or is unavailable, the switch seamlessly connects from the primary to the secondary power source of the corresponding device. When the primary source is restored, the switch connects back to it.
