Chapter 2 - Installation
2.0 Installation Requirements
The PSM-500 VSAT/SCPC Modem is designed for installation in any standard 19-inch
equipment cabinet or rack, and requires 1 RU mounting space (1.75 inches) vertically and 12
inches of depth. Including cabling, a minimum of 15-inches of rack depth is required. The rear
panel of the PSM-500 is designed to have power enter from the left and IF cabling enter from the
right when viewed from the rear. Data and control cabling can enter from either side although
they are closer to the left. The unit may be placed on a table or suitable surface as required.
⇒
CAUTION: There are no user-serviceable parts or configuration settings located
inside the PSM-500 modem case. There is a shock hazard internally at the power supply
module. DO NOT open the modem case unless power is removed for option installation.
⇒
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 PSM-500 Modem was carefully packed to avoid damage and should arrive complete with the
following items for proper installation:
1. PSM-500 Modem Unit. L-Band Units may include an external BUC power supply.
2. Power Cord, 6 foot with applicable AC connector.
3. Installation and Operation Manual plus other information on CD.
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 PSM-500 Modem unit is shipped fully assembled and does not require removal of the covers
for any purpose in normal installation. All normal hardware configuration, including setting the
data interface type and IF impedance is under software control. The type of Feature Sets, FEC
Options and Interface Options installed can be read from the LCD display on the front panel
under
<Unit: Status – >
column by scrolling down after initial application of power.
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 world-wide
application using from 90 to 264 VAC (100 to 240 VAC +/- 10%).
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. The modem
units may be stacked one on top of the other to a maximum of 10 consecutive units before
