Installing The System In Three Rows - Nortel Meridian Companion Installation And Maintenance Manual

Installing the system in three rows

P0725810 Issue 3.0
If horizontal space is limited, install the system in three rows. See the
figure, "Recommended three-row installation"and keep the
following points in mind:
• Three-row installation requires three 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 top and
bottom left and right hand modules.
• The following figure 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 110 cm horizontal distance (55 + 55 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 to a maximum of four modules in the middle row.
• Mount the remaining Base Station and Line Modules in rows
above and below the Controller. Mount them to the left and right
of a vertical line centered on the Controller to a maximum of 4
modules per row.
• The recommended distance between the rows for thermal
dissipation and fiber cable connections is 15 to 20 cm.
• When you mount systems that are significantly smaller than 12
modules, leave room for future expansion and power
requirements.
• This installation does not take into account space or power
requirements for the distribution blocks or RPIs.
