In some instances, you may want to power Base Stations with plug-
top power supplies. See Appendix E for more details on installing e
system in two rowsBase Stations powered by plug-top power
supplies.
If vertical space is limited, install the system in two rows. See the
figure, "Recommended two-row installation" and keep the following
points in mind:
• Two-row installation requires two power cords to the mains outlet
(maximum distance 1.5 m) and four power bars. (The power bars
are shown outside the troughs in the figure. This is for the sake of
clarity only).
• The longest fiber cable run from the Controller is to the bottom
left and right hand modules.
• Figure 3 shows a 12 Module System with nine Line Modules and
three Base Station Modules. However, the combination of Base
Station and Line Modules will vary according to your
requirements.
• The 130 cm horizontal distance (65 + 65 cm) shown in the figure
is the maximum possible distance. The actual distance depends
on the combination of Base Station and Line Modules installed.
• Center the Controller in the top row.
• Place the Base Station and Line Modules to the right and left of
the Controller.
• Mount the remaining Base Station and Line Modules in the row
above or below the Controller. Mount them to the left and right of
a vertical line centered on the Controller to a maximum of six
modules.
