Section 2 - Installation
2.0 Installation Requirements
The DMD2401 LB/ST Modem is designed to be installed within any standard 19-inch wide equipment
cabinet or rack, and requires 2 rack units of mounting space (3.5 inches) vertically and 21-inches of
depth. Including cabling, a minimum of 23-inches of rack depth is required. The rear panel of the
DMD2401LB/ST is designed to have power enter from the left and IF cabling enter from the center when
viewed from the rear of the modem. Data and control cabling can enter from either side although they
are closer to the right. The unit can be placed on a table or suitable surface if required.
There are no user-serviceable parts or configuration settings located inside the DMD2401 LB/ST
chassis. There is a potential shock hazard internally at the power supply module. DO NOT open
the modem case.
⇒ ⇒
CAUTION: Before initially applying power to the modem, it is a good idea to disconnect the
transmit output from the operating satellite ground station equipment. This is especially true if the
current modem configuration settings are unknown, where incorrect setting could disrupt existing
communications traffic.
2.1 Unpacking
The DMD2401 LB/ST was carefully packaged to avoid damage and should arrive complete with the
following items for proper installation:
1. DMD2401 LB/ST Modem Unit.
2. Power Cord, 6-foot with applicable AC connector.
3. Installation and Operation Manual.
2.1.1 Removal and Assembly
If using a knife or cutting blade to open the carton, exercise caution to ensure that the blade does not
extend into the carton, but only cuts the tape holding the carton closed. Carefully unpack the unit and
ensure that all of the above items are in the carton. If the Prime AC power available at the installation
site requires a different power cord/AC connector, then arrangements to receive the proper device will
be necessary before proceeding with the installation.
The DMD2401 LB/ST unit is shipped fully-assembled and does not require removal of the covers for any
purpose in installation. Should the power cable AC connector be of the wrong type for the installation,
either the cable or the power connector end should be replaced. The power supply itself is designed for
universal application using from 100 to 240 Vac, 50-60 Hz, 1.0 A.
2.2 Mounting Considerations
When mounted in an equipment rack, adequate ventilation must be provided. The ambient temperature
in the rack should preferably be between 10
°
and 35
°
C, and held constant for best equipment operation.
The air available to the rack should be clean and relatively dry. Modem units should not be placed
immediately above a high heat or EMF generator to ensure the output signal integrity and proper receive
operation.
