D-LINK DPS-700 Redundant Power Supply Unit

The DPS-700 redundant power supply (RPS) is designed to conform to the wattage requirements of D-Linku2019s Ethernet and Gigabit switches. It is an external RPS unit enclosed in solid metal case with sockets to AC or DC power sources on one end, and connect to a switchu2019s internal power supply on the other end. The RPS provides 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. The DPS-700 also supports 1+1 power capabilities. When cascading the DPS-700 with a deviceu2019s internal power supply, the power system can provide an additional power budget to the PoE switch. Redundant Power Backup Each D-Link RPS is equipped with an integrated detection circuit that continuously monitors the switchu2019s 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 Supply The DPS-700 is 19-inch standard-size rack mount power supply designed to improve flexibility in supporting PoE (Power over Ethernet) equipment.,
