Installation

2.1 Unpacking

The DMD20 Universal Satellite Modem was carefully packaged to avoid damage and should
arrive complete with the following items for proper installation:
DMD20 Modem Unit
Power Cord, with applicable AC Connector
Installation and Operation Manual

2.2 Removal and Assembly

The DMD20 Modem Unit is shipped fully assembled. It does not require removal of the covers for
any purpose in installation.
Always ensure that power is removed from the DMD20 before removing
or installing any optional modules. Failure to do so may cause damage
to the equipment.
Carefully unpack the unit and ensure that all of the above items are in the carton. If the available
AC mains power at the installation site requires a different cordset from the one included in the
package, then a suitable and approved cordset (for the country where the equipment is to be
installed) will be required before proceeding with the 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
AC application. See specifications for appropriate voltages and currents.

2.3 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. The
modems may be stacked one on top of the other to a maximum of 10 consecutive units before
providing one (1) RU of space for airflow. Modems should not be placed immediately above a
high-heat or EMF Generator to ensure the output signal integrity and proper receive operation.
Do not mount the DMD20 in an unprotected outdoor location where there is direct contact with
rain, snow, wind or sun. The only tools required for rack mounting the DMD20 are four (4)
customer supplied rack-mounting screws and the appropriate screwdriver. Rack mounting
brackets are an integral part of the front bezel of the unit and are not removable.
