About This Guide

The D-Link DPS-200A, 500A, and 500DC
are redundant power supplies designed to be
mounted into a standard rack and provide an
affordable solution to provide a constant power
source. This guide gives step-by-step instructions
for setting up the DPS-200A, 500A, and 500DC
with a switch that supports power over a 14-pin
DC power cable. Please note that the model you
have purchased may appear slightly different
from those shown in the illustrations.
For more detailed information about your switch,
its components, making network connections,
and technical specifications, please refer to the
User's Guide included with your switch.
Introduction
A redundant power supply provides a low-cost,
simple solution to the equally simple yet vexing
problem of internal power supply failure, which
can result in the shutdown of a single switching
device or an entire network.
With a redundant power supply connected, an
integrated detection circuit 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 switch
and 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.
Description
The DPS-200A, DPS-500A and DPS-500DC
are redundant power supply units designed
to conform to the wattage requirements of the
switches being supported.
The DPS-200A, DPS-500A and DPS-500DC
can connect to the master switch using a 14-pin
DC power cable. A standard, three-pronged
AC power cable connects the redundant power
supply to the main power source.

Rack Installation

The single RPS DPS-200A, 500A, and 500DC
can be installed to the standard rack via the RPS
rack DPS-800. The DPS-800 is a standard-size
rack mount (1.25U in height) designed to hold
up to 2 redundant power supplies. Installed RPS
units can be DPS-200As, DPS-500As, DPS-
500DCs, or a combination of the above.
