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.

• only connect like circuits. In other words, connect SELV (Secondary Extra
Low Voltage) circuits to SELV circuits and TN (Telecommunications
Network) circuits to TN circuits.

2.1
Introduction
This chapter tells you how to install the power supplies, the rack controller
card, andmodemcards into your MultiModemManager CardCage. Thecage
itself may be installed in an industry-standard 19-inch wide rack cabinet, or
placed on a securetabletop. Figure 2-1, below, displays the front of a fully
loaded rack with one controller card, two power supplies, and a full
complement of 16 modem cards.
modem card
Controller
Power Supply
Power Supply
The rack can work with one or two
PS4800 power supplies. A second
recommended power supply provides the
system with a "redundant" function. If
any of the three outputs on either supply
fails, or is low, the other supply takes
over, producing all of the power required
to run the system, without any switchover
period. (This is assuming that both power
supplies are powered on; with both
powered on and operational, they share
the load.)
This module contains the processor and
memory for intelligent operation of the
rack. The back panel contains an RJ11
connection for Network UTP attachment
to another rack, to an Active Hub, or to a
manager node. The front panel provides
16 two-color LEDs for rack controller card
status, and a 3-digit 7-segment display for
cage number/node ID display. A 3-position
connector on the back panel is available
for attaching one of several warning alarm
systems (such as audio, video or DTR
dialer systems).

MR4800 Controller, and sixteen modem cards.

2.2
Hardware Installation Procedure
WARNING: When the modem rack is connected to the phone lines, it is
possible for hazardous voltages to be present within the modem
rack. To avoid injury, all modems should be installed in the rack,
and any card slot that does not have a modem in it should be
fitted with a blank panel prior to making any connections from the
rack to the phone lines. All openings on the front of the modem
rack, including the sixteen modem slots, the controller card slot,
and the two power supply slots should remain covered by either a
blank panel or the appropriate module at all times, unless the
connectionsto the phonelines are removed.
1. Place the rack in a standard 19-inch wide rack cabinet and secure
(refer to the rack cabinet manual); or set it on a secure tabletop.
2. Loosen rack front panel access screws.
3. Installthepower supply module(s) in properlocation(s), by aligning the
power supply flanges in the card guides. A positioning pin will align the
connectors at the back interior of the rack. Press firmly to mate the
connectors. Secure with provided screw.
4. Installblankpanels where needed to coverany unused power supply,
controller card, or modem card slots.
5. Connect the cables at the rack back panel (refer to Figure 2-2, 2-3 or
2-4).
6. Install the rack controller card in proper location by aligning the printed
circuit board in the card guides. Press firmly to mate connector and
secure. For full information on configuring the controller, see your Rack
Controllermanual.
7. Turn rack Power Switch On ( |). A self-test is performed to confirm front
panel operation. If a controller card is installed, you will observe the
following:
• the seven segment display shows all 8s;
• the green LEDs light, then go out;
• the red LEDs light, then go out;
• and the rack Node ID is finally displayed.
8. Powerdownthemodemrack.

9. Determine the modem slot(s) to be used and remove front panel slot(s) if
necessary. Insert the MultiModem cards. Align modem module in card
guides and press firmly to mate the connectors.
10. Power on the rack.
