Kirjeldus

DPS-500 redundant power supply (RPS) is designed to conform to the wattage requirements of D-Link’s Ethernet and Gigabit switches. This is external RPS enclosed in solid metal cases with sockets to AC or DC power sources on one end, and connectors to the switch’s internal power supply on the other end. DPS-500 provides a low-cost, simple solution to the problem of an inadvertent failure of the internal power-supply of the Ethernet switch, which can result in the shutdown of that switching device, 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.
 
Redundant Power Backup
DPS-500 is equipped with an integrated detection circuit that continuously monitors the switching device’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 a single failure of a network device power supply.
 
Easy and Flexible Deployment
Deployment of a DPS-500 does not necessitate any change in configuration of the LAN switch. DPS-500 is equipped with a universal internal power supply, and can be connected to any AC main power source from 90VAC to 264VAC, 47Hz to 63Hz through a standard AC power cable. 
 
DPS-500 Redundant Power Supply
DPS-500 can be installed as independent power supply unit, or placed inside a DPS-800 or DPS-900 chassis. The chasses are 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.
