1.1

Introduction

The

CC4800 card cage

is the housing for the MultiModemManager,
Multi-Tech Systems’ high-density modem management system. The modem
rack may contain one rack controller module, two power supply modules
(one is required, and two are recommended), and 48 modems (16 modem
cards, with three modems per card). You may connect phone lines to the
rack by using either RJ11, or optional RJ21 connectors.

You may control up to 254 MultiModemManager racks from a single
PC running the MultiModemManager software, which operates under
Windows™ 3.1.

Model CC4800/11 consists of a card cage with a backplane of 48 RJ11
(6-pin modular) phone connectors, and one PS4800 power supply.
It supports dial-up lines.

Model CC4800/21 consists of a card cage with a backplane of 6 RJ21
(50-pin amphenol) phone connectors, and one PS4800 power supply.
It supports dial-up lines, and 2-wire and 4-wire leased lines.

1.3
Special Considerations for CC4800 48 Volt Card Cages

The power supply input screw terminals, located on the bottom right portion
of the back of the card cage, are intended to serve as the disconnect device.

The power requirement is DC, 42-54V, 7A. For continued protection against
risk of fire, replace with same type and rating of fuse. The fuse size is
T7.0A, 250V.

The rack back panel on your CC4800 48 Volt Card Cage does not appear as
illustrated in Chapter Two of this manual. Instead of an AC Power outlet and
fuse on the bottom right of the cage, you will find a 3-terminal power input
strip and an hexagonal-shaped fuse holder. The power input strip is labelled,
from left to right, negative (-), positive (+) and earth ground:

1.4
General Installation Considerations

This equipment should only be installed by properly qualified service
personnel.

You may be installing components into a CC4800 card cage for the first time,
or you may be re-installing or replacing components. Please observe the
following:

• unpack hardware carefully.

• perform a visual inspection of the hardware. If you are concerned about
the condition of your rack, call Technical Support.

• make sure that the flat ribbon cable on the back of your card cage is
properly seated.

• for a first-time installation, install your power supplies, then power-up the
rack to make sure the supplies work, then power the unit down before
installing the other components.

• consult the manuals for your other component(s) (Power Supply, Rack
Controller, and Modem Cards) to customize your settings before you install
it (them) into the Card Cage. If you are installing more than one rack, you
will need to change the Node ID of the additional controller(s). You will
need to see the Controller manual for full instructions.
