D-Link DPS-500A Power supply
The DPS-Series of redundant power supplies (RPS) provide protection from damaging surges, spikes and 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 D-Link DPS-500A and DPS-700 redundant power supplies (RPS) perfectly compliment D-Link’s Ethernet and Gigabit switches supporting full output power for the switch and maximizing 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 the 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. Each RPS is equipped with a universal internal power supply and can be connected to an AC power source from 90 V AC to 264 V AC, 47 Hz to 63 Hz through a standard AC power cable.
Modular Redundant Power Supply: D-Link DPS-500A
The D-Link DPS-500A is a modular redundant power supply which can be installed as an independent power supply unit or placed inside a DPS-800 Rack-mount chassis. The chassis is designed for mounting in a standard 19-inch equipment rack. Multiple power supplies can be placed inside a chassis, from which they can connect to the switches mounted in the same rack. 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.
Rack Mounted Power Supplies: DPS-700
The DPS-700 is a 19-inch standard-size rack mount power supply designed to improve flexibility in supporting PoE (Power over Ethernet) equipment. It supports 1+1 power capabilities and when cascaded with a device’s internal power supply, the power system can provide additional power budget to the device.
Rack-Mount Chassis: DPS-800
The DPS-800 chassis can accommodate up to two D-Link DPS-500A modules to an equipment rack.
