DPS-500A
140 watts Redundant Power Supply
The DPS-500A redundant power supply (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, this redundant power supply can maximize the power availability of the switching device.
– Can be installed as stand-alone power supply units or mounted in 19-inch multi-slot chassis
– Hot swappable when installed in chassis
– Up to 140 watts output power
– Provide backup power for switch’s built-in power supply
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.
Easy and Flexible Deployment
Deployment of a DPS series device does not require any change in the configuration of the LAN switch.
Rack Mounted Power Supply
Using a chassis, users can save space while allowing for clean cabling. All redundant power supply units installed in the chassis connect directly to their power sources, and they are hot-swappable.
Modular Redundant Power Supply
The DPS-500A is a modular redundant power supplies which can be installed as independent power supply units or placed inside a DPS-800 or DPS-900 Rack-mount chassis.
Rack Mounted Power Supply
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. The DPS-800 chassis can accommodate up to two DPS-200, DPS-300 or DPS-500/500DC modules to an equipment rack.
