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-Link’s 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 switch’s 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.
Redundant Power Backup
Each D-Link RPS is equipped with an integrated detection circuit that continuously monitors the
switch’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 going down due to failure of a single network device power supply.
Easy and Flexible Deployment
Deployment 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.
Rack Mounted Power Supplies: DPS-600/700
The 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 device’s internal power supply, the power system can provide an additional power budget to the device.
