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

Switch Connection

Caution: The redundant power supply should

be disconnected from its power source before

connecting to the switch. Directly connecting

a powered RPS to the switch may cause

damage to the switch’s internal power supply.

Insert one end of the DC power cable into the receptacle on

the switch and the other end into the redundant power

supply.

Caution: Do not connect the DPS-700 to the

switch using the 14-pin DC power cable. The

equipment may be damaged if using this

cable instead of the correct 22-pin DC power

cable.

Power Connection

Connecting AC Power (DPS-200/300/500/600/700)

Using a standard AC power cable, connect the redundant

power supply to the main AC power source. A green LED

on the front of the DPS-200/DPS-300/DPS-500/DPS-600

will glow to indicate a successful connection.

Connecting DC Power (DPS-500DC)

1. Firmly attach the DC power source to the negative and

positive contacts on the wiring assembly.

 The negative pole (-)

connects to the -48V contact.

 The positive pole (+)

connects to the -48V RTN

contact.

 If available, an earth ground

may be connected to the

center contact post.

2. Tighten the contact screws to secure the connection.

No change in switch configuration is necessary when

connecting to the RPS.
