Overview

The AT-WDRPS-80 is a DC Redundant Power Supply (RPS) for the AT-WD1008
Multiplexer chassis. When installed, the unit shares the load of powering the
chassis with the standard power supply that comes pre-installed in the chassis. If a
power supply fails, the remaining unit provides all power to the system, thereby
preventing a network failure. The power supply is hot-swappable, meaning that
you can install it while the chassis is powered ON.

The Allied Telesyn web site at www.alliedtelesyn.com contains the most recent
documentation, software, and technical information for all of our products. For
details on the features and functions of your Allied Telesyn AT-WD1008 chassis and

Installing the AT-WDRPS-80 Power Supply

Caution

Before installing the module, refer to the AT-WD1008 Installation Guide for
electrical safety and emission information.

Caution

Do not install the AT-WDRPS-80 module in an AT-WD1008 chassis intended
for AC power. A DC powered chassis has two DC terminal blocks on the back
panel.

Note

The AT-WDRPS-80 unit can be installed while the multiplexer is powered ON.
You do not need to power OFF the multiplexer to install the RPS.

1. Loosen the two thumbscrews that secure the blank faceplate over the right­hand redundant power supply expansion slot located on the front panel of the
AT-WD1008 Multiplexer and remove the cover.

Wiring the AT-WDRPS-80 Power Supply

Warning

As a safety precaution, a 10 Amp circuit breaker should be installed at the
supply end of the cable to be used with this LAN equipment.

ALWAYS connect the wiring to the LAN equipment first before connecting
the wiring to the breaker. To avoid the danger of physical injury from
electrical shock, do not work with HOT feeds. Always be sure that the
breaker is in the OFF position before connecting the wiring to the breaker.

Note

A tray cable is required to connect the power source if the unit is powered by
centralized DC power. The tray cable must be UL listed Type TC tray cable and
rated at 600 V and 90 degree C, with three conductors, minimum 14 AWG.

1. On the rear side of the chassis is a DC terminal block labeled POWER SUPPLY B.
Starting from the left side of the terminal block, identify the positive, frame
ground, and negative terminals using either the diagram adjacent to the
terminal block or the illustration here:

3. Connect the frame ground wire to the terminal marked with the ground
symbol by inserting the wire into the terminal and tightening the connection
with a flathead screwdriver.

Warning

When installing this equipment, always ensure that the frame ground
connection is installed first and disconnected last.

4. Connect the positive feed wire to the terminal block marked (+).

5. Connect the negative feed wire to the terminal block marked (-).

2. With a 14-gauge wire-stripping tool, strip the three wires in the tray cable
coming from the DC input power source to 8 mm

± 1 mm (0.31 in ± 0.039 in).

Warning

Do not strip more than the recommended amount of wire. Stripping more
than the recommended amount can create a safety hazard by leaving
exposed wire on the terminal block after installation.

8 mm ± 1 mm

(0.31in ± 0.039 in)

Warning

"Safety Hazard"- Check to see if there are any exposed copper strands

coming from the installed wires. When this installation is done correctly
there should be no exposed copper wire strands extending from the
terminal block. Any exposed wiring can conduct harmful levels of electricity
to persons touching the wires.

6. Secure the tray supply cable near the rack framework using multiple cable ties
to minimize the chance of the connections being disturbed by casual contact
with the wiring. Use at least four cable ties separated four inches apart with
the first one located within six inches of the terminal block.

Note

This system will work with a positive grounded or negative grounded DC
system.
