The DPS-200 DPS-300 DPS-500/500DC DPS-600 and DPS-700 redundant power supplies (RPS) are designed to conform to the wattage requirements of D-Links Ethernet and Gigabit switches. They are external RPS units enclosed in solid metal cases with sockets to AC or DC power sources on one end and connect to a switchs internal power supply on the other end. They provide a low-cost simple solution to the problem of an inadvertent failure of the internal power-supply of an Ethernet switch which can result in the shutdown of that switch the devices attached to its ports or an entire network. Supporting full output power for the switch these redundant power supplies can maximize the power availability of the switching device.N/AN/ARedundant Power BackupN/AEach D-Link RPS is equipped with an integrated detection circuit that continuously monitors theN/Aswitchs internal power supply. In the event of a power interruption the redundant power supply isN/Aimmediately 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 going down due to failure of a single network device power supply.N/AN/AEasy and Flexible DeploymentN/ADeployment of a DPS series device does not require any change in the configuration of the LAN switch. With the exception of the DPS-500DC each RPS is equipped with a universal internal power supply and can be connected to any AC power source from 90 V AC to 264 V AC 47 Hz to 63 Hz through a standard AC power cable. The DPS-500DC provides the same output power as the DPS-500 but connects to a DC power source instead of an AC power source.N/AN/ARack Mounted Power Supplies: DPS-600/700N/AThe DPS-600 and DPS-700 are 19-inch standard-size rack mount power supplies designed to improve flexibility in supporting PoE (Power over Ethernet) equipment. The DPS-700 also supports 1+1 power capabilities. When cascading the DPS-700 with a devices internal power supply the power system can provide an additional power budget to the device.
