DMD15/DMD15L IBS/IDR Satellite Modem Installation
TM051 - Rev. 5.8 2-1
Section 2 – Installation
2.0 Installation Requirements
The DMD15/DMD15L Modem is designed to be installed within any standard 19-inch wide
equipment cabinet or rack, and requires one rack unit (RU) of 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 of the DMD15/DMD15L is designed to have power enter from the right
and IF Cabling enter from the left 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 DMD15/DMD15L Chassis. There is a potential shock hazard internally at
the power supply module. DO NOT open the DMD15/DMD15L 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 DMD15/DMD15L configuration settings are
unknown, where incorrect settings could disrupt existing communications
traffic.
2.1 Unpacking
The DMD15/DMD15L Modem was carefully packaged to avoid damage and should arrive
complete with the following items for proper installation:
1. DMD15/DMD15L Modem 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 DMD15/DMD15L Modem Unit is shipped fully assembled and does not require removal of the
covers for any purpose in installation. The only replaceable assembly in the unit is the Universal
Interface Module (UIM).
