Perfect Complement for D-Link Ethernet and Gigabit Switches

The DPS-500 redundant power supply (RPS) is designed to conform to the wattage requirements of D-Link’s Ethernet and Gigabit switches. It is an external RPS enclosed in a solid metal case with sockets to AC or DC power sources on one end, and connectors to the 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 the Ethernet switch, which can result in the shutdown of that switch, the devices attached to its ports, or even the entire network. Supporting full output power for the switch, these redundant power supplies can maximize the power availability of the switch.

Modular Redundant Power Supplies: DPS-500

The DPS-500 is a modular redundant power supply which can be installed as an independent power supply unit or placed inside a DPS-800 or DPS-900 rack-mount chassis. The chassis 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.

Redundant Power Backup

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 prevents the network from going down due to failure of a single network device's power supply.

Easy and Flexible Deployment

Deployment of a DPS Series device does not require any change in the confguration of the LAN switch. The DPS-500 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.
