D-Link DPS-500A - Specificaties

The DPS-200A, DPS-500A and DPS-700 redundant power supplies (RPS) are designed to conform to the wattage requirements of D-Link’s Fast Ethernet and Gigabit switches. They provide a low-cost, simple solution to the problem of a failure of the internal power-supply of an 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, these redundant power supplies can maximize the availability of the switching device.\n\nRedundant Power Backup\nEach D-Link® RPS 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.\n\nEasy and Flexible Deployment\nDeployment of a DPS-200A, DPS-500A or DPS-700 does not necessitate any change in configuration of the LAN switch. Each RPS 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.\nThe DPS-200A and DPS-500A power supplies are modular, and can be mounted on benchtop/desktop as independent power supply units, or installed in a DPS-800 chassis, which holds two power supplies and mounts in a standard 19-inch equipment rack.\nThe DPS-700 is a 1U high 19-inch standard-size rack mount power supply designed specifically for D-Link’s PoE switches. Not only does it provide power backup in the event of a power supply failure in the PoE switch, but it also supports PoE power load sharing. It provides an additional 370W of PoE power budget to the switch to support more powered devices.\nAll D-Link redundant power supplies ship with the necessary cables. The one exception is for the DPS-3000-10TC Gigabit switch when used with the DPS-200A power supply. In this case, a DPS-CB150-2PS cable must be separately ordered.\n\nDPS-800 Rack-Mount Chassis\nEach DPS-800 chassis can accommodate up to two DPS-200A or DPS-500A power supply modules in an equipment rack. The DPS-800 occupies 1.25U of rack space and allows users to save space with efficient cabling. All redundant power supply units installed in the chassis connect directly to their power sources and are hot-swappable.\nD-Link RPS Compatibility Chart\n\nDPS-500A:\n- DGS-3450 \n- DGS-3120-48TC \n- DGS-3420-28TC \n- DGS-3420-28SC \n- DGS-3420-52T\n- DGS-3620-28TC\n- DGS-3620-28SC\n- DGS-3620-52T
