Plan the Belowdecks Installation
3
Before you begin, consider the following
installation guidelines for the belowdecks units.
Control Unit and Modem
• Select a mounting location in a dry, well-
ventilated area belowdecks away from any
heat sources or salt spray.
• Be sure the front panels will be easily
accessible to the user.
• Leave enough room at the rear panel to
accommodate the connecting cables.
• You have several options for mounting the
control unit and modem:
Option 1 - Inside the optional case
Option 2 - To a horizontal surface together
using two L-brackets
Option 3 - To a horizontal surface
separately using four L-brackets
NOTE: The control unit and modem are sized to
fit a standard 19" (482.6 mm) equipment rack.
• To use the supplied data and power cables,
the control unit must be located within 100 ft
(30 m) of the antenna. However, you can
order 150 ft (45 m) cables if a longer cable run
is necessary (see Figure 18 on page 11).
Switch and MTA
• To use the supplied Ethernet cables, select a
mounting location within 25 ft (7.5 m) of the
modem (maximum length = 200 ft (60 m)).
• If you install a wireless access point (supplied
by customer), be sure the location provides
adequate WiFi reception. Do not install it in
an area surrounded by metal or near any
electrical devices that emit RF noise.
Remote Service & Support Module
• To use the supplied serial data cable, select a
mounting location within 25 ft (7.5 m) of the
control unit (maximum length = 50 ft (15 m)).
• Be sure the location provides adequate GPRS
cellular reception.
