DMD2401/DMD2401L/DMD2401 IBS/IDR Satellite Modem Installation
TM065 - Rev. 3.3 2-1
Section 2 – Installation
2.0 Installation Requirements
The DMD2401 can be installed within any standard 19-inch equipment cabinet or rack, and
requires 1 RU mounting space (1.75 inches) vertically and 21 inches of depth. Including cabling,
a minimum of 23-inches of rack depth is required. The rear panel is designed to have power
enter from the left and IF cabling enter from the right when viewed from the rear of the unit. Data
and control cabling can enter from either side although they are closer to the left. 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
chassis. There is a potential shock hazard internally at the power supply
module. DO NOT open the DMD2401 chassis under any circumstances.
Before initially applying power to the unit, it is a good idea to disconnect the transmit
output from the operating ground station equipment. This is especially true if the
current DMD2401 configuration settings are unknown, where incorrect settings could
disrupt existing communications traffic.
2.1 Unpacking
The DMD2401 Modulator was carefully packaged to avoid damage and should arrive complete
with the following items for proper installation:
1.
DMD2401 Unit.
2. Power Cord, 6-foot with applicable AC connector.
3. Installation and Operation Manual.
2.2 Removal and Assembly
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 Modulator is shipped fully assembled. It does not require removal of the covers for
any purpose in installation. The only replaceable assembly in the unit is the data interface and is
not intended to be accomplished in the field. 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, 1.0A.
