Chapter 1 - Introduction
The CC1600 is a generic rack that accommodates a variety of rackmount modems and DSUs. The CC1628
series is designed specifically for V.34 modems. Both rack models come in -11L and -21 versions. The -11L
version connects to standard RJ11 telephone phone cords. The -21 version has three 50-pin connectors for
dial-up and 2-wire or 4-wire leased lines. Both models are equipped for universal AC input or
-48v DC. Finally, both models are available with either a single power supply or dual (redundant ) power
supplies for uninterrupted power. A single power supply can maintain a full complement of modems.
The CC1600-series rack makes it easy for you to monitor your data communications. Each modem has its
own set of LEDs, with separate indicators for Receive Data, Transmit Data, Carrier On, Speed, Off Hook,
Data Terminal Ready, Ring Indicator, and Error (Out-of-Service and Busy).
The rack measures 19" wide, 7" high, and 15" deep. The rack is usually mounted in the same cabinet as your
computer, or can be enclosed in a separate cabinet of its own. Modems are installed by simply opening the
rack front door and sliding in the modems. RS232C cables and phone cords are connected to modem
connectors at the back of the rack.

Chapter 2 - Installation
2.1 Introduction
Multi-Tech rackmount modems are generally used in a central site computer environment (i.e., connected to
a mini or mainframe computer) to automatically answer incoming calls from remote users.
Command mode should be disabled unless you wish to give the modem commands. Leaving command
mode enabled offers the possibility of a user calling into the modem and reconfiguring it, or causing it to dial
out. Refer to the appropriate modem owner’s manual to configure the modem for your application.
2.2 Safety Warnings
Never install telephone wiring during a lightning storm.
Never install telephone jacks in wet locations unless the jack is specifically designed for wet locations.
Never touch uninsulated telephone wires or terminals unless the telephone line has been disconnected at
the network interface.
Use caution when installing or modifying telephone lines.
Avoid using a telephone (other than a cordless type) during an electrical storm. There may be a remote risk
of electrical shock from lightning.
Do not use the telephone to report a gas leak in the vicinity of the leak.
2.3 Safety Recommendations
The following safety recommendations should be observed when installing Multi-Tech CC1600-series
modem racks.
Ensure proper installation of the CC1600-series modem racks in a closed or multi-unit enclosure by
following the recommended installation as defined by the enclosure manufacturer. Do not place the
CC1600-series modem rack directly on top of other equipment or place other equipment directly on top of the
CC1600-series rack.
If installing the CC1600-series modem rack in a closed or multi-unit enclosure, ensure adequate airflow
within the rack so that the maximum recommended ambient temperature is not exceeded.
Ensure that the CC1600-series modem rack is properly connected to earth ground via a grounded power
cord. In the event that a power strip is used, ensure that the power strip provides adequate grounding of the
attached equipment.
Ensure that the mains supply circuit is capable of handling the load of the CC1600. Refer to the power label
on the equipment for load requirements.
Maximum recommended ambient temperature for the CC1600 is 50° C (120° F).
This equipment should be installed only by properly qualified service personnel.
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.

2.4 Installation
Perform the following procedure to install the CC1600-series modem rack and install up to 16 modems in the
rack.
1. Unpack the rack and check all items against the shipping list to ensure that you have received the correct
items. Rack components include:
Rack
Power Cord
Owner's Manual
2. Inspect the rack for visible shipping damage. If damage is observed, do not power-on the rack; contact
Multi-Tech's Technical Support for advice (refer to Chapter 3).
3. If no damage is observed, mount the rack in a standard 19-inch wide rack enclosure. Mounting
hardware should be provided with the rack enclosure.
4. If power supply is not installed in rack, refer to the following section for power supply installation. If the
power supply is already installed, proceed to step 5.
5. Open the rack front door.
6. Unpack the modems to be installed in the rack.
7. Refer to the RackMounted Modem Owner's Manual for the switch settings and parameters which pertain
to your application (dial-up/leased-line).
8. Slide a modem into one of the 16 available slots. The component side of the card should be to the right
as in Figure 2-1. The modem's gold edge connector will mate with the rack's backplane. The edge
connector is offset vertically so the modem cannot be inserted upside down.

9. Firmly seat the modem card into the backplane connector.
10. Repeat steps 7 through 9 for the remaining modems.
11. Connect an RS232C cable to the DB25 connector (25-pin female connector) on the backplane of the
rack. Start by connecting the RS232C cable to the right-most channel (slot 1) as viewed from the back of
the rack.
Note: Any cables connected to the computer should be shielded to reduce radio frequency interference.
Keep track of which computer channel belongs to which modem in the rack. Most computer interface buses
are grouped in sixteens, which enables you to match modem and computer channel numbers.

12. If you are connecting your phone line directly to an RJ11 jack on the backplane of the rack, plug the
telephone cord into the RJ11 jack on the appropriate modem.
If you are connecting a -11L rack to leased lines or leased lines with dial back-up, a Dial/Leased Splitter
is required between the leased line jack and the RJ11 jack on the backpanel of the rack. The single
RJ11 plug connects to the RJ11 jackon the backpanel of the rack. The RJ11 jack labeled Leased
connects to the leased line connector. If dial-back up is used, the RJ11 jack labeled dial should be
connected to the dial-back up line.
Note: The Dial/Leased Splitter is a custom part (a "Y" cable) which includes an RJ11 plug that plugs into the
RJ11 jack on the backplane of the rack and is a 5-inch-long six-conductor cable terminated at two RJ11
jacks. One jack is labeled Leased and the other Dial.

Chapter 2 - Installation
If you are connecting your phone lines (-21 series rack) to the 50-pin connector on the backplane of the
rack, plug the appropriate phone cable into the appropriate 50-pin connector (RJ21X). RJ21X
connectors are TN circuits.
Note: Three 50-pin connectors are mounted on the back of the -21 series rack backplane (See Figure 2-3).
The left 50-pin connector (labeled Dial-Up/2-Wire Leased Line) is used to connect all the modems in the -21
series rack to dial-up phone lines. When 4-wire leased lines are being connected, the two right 50-pin
connectors (labeled 2-wire Lease Line/4-wire Transmit Pair on the right and 4-wire Receive Pair in the
center) are used to connect the rack to leased lines. When connecting to 2-wire leased lines, you must first
determine if your modem has dial back-up capability. If it does, then use the right connector. If it does not,
then use the left (2-wire Lease Line) connector.

6. Return to the rack installation procedure to continue installing the rack.

14
Chapter 2 - Installation
2.5 Powering Up
Once the power switch is turned on, the green LED on the power supply(s) should be lit and the modems
perform a diagnostic self-test, indicated by the speed LEDs flashing in sequence for approximately two
seconds. If none of the modems have power to them or the power supply LED(s) is not lit, check the power
cord connection and check that the AC outlet is live. If one of the green power supply LEDs on the front of the
rack is not lit, then one of the redundant power supplies may be defective or not installed correctly (i.e., not
making proper contact).
