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-200, DPS-300, DPS-500, DPS-500DC, DPS-600

and DPS-700 are redundant power supply units designed to

conform to the wattage requirements of the switches being

supported. DPS-200 operates at 60 watts; DPS-300

operates at 90 watts, DPS-500/500DC at 140 watts, DPS-

600 at 500watts, and the DPS-700 at 589 watts.

The DPS-200, DPS-300, DPS-500, DPS-500DC, and DPS-

600 can connect to the master switch using a 14-pin DC

power cable. Similarly, the DPS-700 uses a 22-pin DC

power cable. A standard, three-pronged AC power cable

connects the redundant power supply to the main power

source.

Installation of the RPS

The single RPS DPS-200, 300, 500, and 500DC can be

installed to the standard rack via the RPS rack DPS-800

and DPS-900. DPS-900 is a standard-size rack mount (5U

in height) designed to hold up to 8 redundant power

supplies. The DPS-800 is also a standard-size rack mount

(1.25U in height) designed to hold up to 2 redundant power

supplies. Installed RPS units can be DPS-200s, DPS-300s,

DPS-500s, DPS-500DCs, or a combination of the above.

NOTE: The DPS-500DC can only be

inserted into a DPS-800
