D-Link DPS-500A Redundant Power Supply

The DPS-200A, DPS-500A and DPS-700 redundant power supplies (RPS) are designed to conform to the wattage requirements of D-Link’s Fast Ethernet and Gigabit switches. They provide a low-cost, simple solution to the problem of a failure of the internal power-supply of an Ethernet switch, which can result in the shutdown of that switching device, the devices attached to its ports, or an entire network. Supporting full output power for the switch, these redundant power supplies can maximize the availability of the switching device.

Each D-Link® RPS is equipped with an integrated detection circuit that continuously monitors the switching device’s internal power supply. In the event of a power interruption, the redundant power supply is immediately triggered so that the LAN switch and its connected devices can continue providing service. This results in a more reliable network infrastructure and protects the network from a single failure of a network device power supply.

Deployment of a DPS-200A, DPS-500A or DPS-700 does not necessitate any change in configuration of the LAN switch. Each RPS is equipped with a universal internal power supply and can be connected to any AC main power source from 90VAC to 264VAC, 47Hz to 63Hz through a standard AC power cable.
