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.
ï‚· The negative pole (-)
connects to the -48V contact.
ï‚· The positive pole (+)
connects to the -48V RTN
contact.
ï‚· 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.
