Installing the Redundant Power Supply (RPS)

The 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 unit enclosed in solid

metal case with sockets to connect AC or DC power sources on one end, and to connect

to a switch’s internal power supply on the other end. The RPS provides 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.

CAUTION: Do not connect the RPS to AC power before the DC power cable is

connected. This might damage the internal power supply.

DPS-500A and DPS-500DC Redundant Power Supplies

This RPS (DPS-500A and DPS-500DC) can be connected to the Switch’s RPS port using

the DPS-CB150-2PS (HW: B1) DC power supply cord. It is important to notice that the

RPS can supply power to one or two DGS-3000 Switches at the same time.
