AC to DC Power Supply
The AC to DC Power Supply consists of a power supply chassis and one or two
power modules.
The power supply chassis with one power module is Feature
Number 8800-F2-900.
The power module is Feature Number 8800-F2-901.
The AC to DC Power Supply can be used to supply redundant power to a single
8820 Broadband Access Concentrator (BAC), or non-redundant power to one or
two BACs.
The maximum DC output of each power module is 825 watts. Do not exceed
825 watts in your BAC configuration.

8820-A2-GN20 8820 Broadband Access Concentrator Installation Guide
2 June 2004 8800-A2-GZ41-20
Installation Overview
Installation of the AC to DC Power Supply requires the following steps:
1. Mount the power supply in your rack.
2. Connect the power supply to the 8820 BAC.
3. Connect the power supply to an AC power source.
Be sure to register your warranty at www.paradyne.com/warranty.
Mounting the Power Supply
Procedure
To mount the power supply:
1. Remove the power modules from the power supply chassis.
2. The power supply is shipped with its mounting brackets set up for a 19-inch
rack. If you are installing the power supply in a 23-inch rack, remove the
mounting brackets from the power supply chassis, turn them, and reinstall
them with their short sides against the body of the power supply chassis.
3. Determine where the power supply will be placed in the rack. The power
supply should be placed under the BAC or BACs it will supply power to.
4. If the rails of your rack have unthreaded screw holes, install self-retaining nuts
on the rails where the mounting brackets will be fastened.
5. Line up the mounting brackets with the front rail holes.
6. Loosely install the bottom screws first and then the top screws.
7. Tighten all screws firmly with a Phillips screwdriver.
8. Replace the power modules removed in Step 1.

Connecting the Power Supply to the BAC
Power Entry Modules (PEMs) installed in the front of the BAC provide –48 VDC
power distribution, a 35-amp circuit breaker, power line filtering and input power
monitoring. They are designated PEM A (on the left) and PEM B (on the right). All
input power is distributed to the system via the PEMs, so that if one PEM or one
power source fails, power will be supplied through the other PEM automatically
without service interruption. Power inputs may be connected to the PEMs at the
front of the BAC using the PEM’s terminal blocks, or at the terminal block on the
back of the BAC. This document shows the recommended technique, with
connections at the rear of the BAC. See the 8820 Broadband Access Concentrator
Installation Guide for more information.
Review the following procedures and determine which is appropriate for your
configuration. The recommended configuration is two power modules connected
to one BAC (providing a redundant power source). For all configurations:
Make sure that the AC power cords are not connected to the power supply
until other wiring is completed.
Use 8 AWG solid or stranded wire.
Attach ring tongue terminals to the ends of the wires to be connected to the
BAC power terminal block. See the 8820 Broadband Access Concentrator
Installation Guide for more information.
Attach ring tongue terminals to the ends of the wires to be connected to the
power supply.
Strip 1/2 inch of insulation from the ends of the wires to be fastened at split
bolt connectors or the grounding lug of the BAC.
CAUTION:
The following procedures must be performed by a trained technician.

Providing Redundant Power to One BAC (Recommended)
Procedure
To connect two power modules to one BAC (see Figure 1):
1. If none exist, install split bolt connectors or a grounding block near the rack
where the power supply and BAC reside.
NOTE:
Split bolt connectors are not supplied.
2. Connect:
— The grounding lug of the BAC to an earth ground.
— The PWR A –48V terminal of the BAC to the –48VA terminal of the power
supply.
— The PWR A RTN terminal of the BAC to a split bolt connector.
— The 0VRA terminal of the power supply to the split bolt connector.
— The PWR B -48V terminal of the BAC to the –48VB terminal of the power
supply.
— The PWR B RTN terminal of the BAC to a split bolt connector.
— The 0VRB terminal of the power supply to the split bolt connector.
— The split bolt connectors to an earth ground.
3. Verify that the power switches of the PEMs and the power modules are in the
off (0) position.
4. Insert the AC power cords into the Input A and Input B sockets at the rear of
the power supply. Plug the other ends into an AC power source.
5. Turn to the On (1) position the power switches of PEM A and PEM B of the
BAC and both power modules. Verify that the POWER LEDs at the front of the
power modules and the POWER A and POWER B LEDs at the top of the BAC
are on.
