About This Guide
The D-Link DPS-200A, DPS-500A, DPS-500DC, and
DPS-700 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, 500DC und 700 with
a switch that supports power over a 14-pin or 22-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, DPS-500DC, and
DPS-700 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 while the DPS-700 uses a 22-pin DC power
cable to connect. 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 into a 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.
