How to get started
2.1 Power requirements
The absolute maximum total power consumption for this module is 6.75 W, of which 4.2 W
are drawn from the +5 V supply, 2.3 W are drawn from the +15 V supply, and 0.25 W are
drawn from the -15 V supply. These numbers include 0.5 W from the +5 V supply for the
optional optical input module, and the calculation of how many modules can be powered by
a single power supply can thus be based on 3.7 W for the SPG-AVA-DMUX and 4.2 W for
the SPG-AVA-DMUX-R.
Note that the module will draw its power from multiple supply voltages. When
calculating the number of modules that can safely be used in one frame, it’s
important to consider each supply voltage separately for the power supply in
question. In general there will be no load-sharing between the supply voltages,
and the number of modules will be limited by the worst-case result from the
individual calculations.
2.2 Physical connections
Figure 2: The cable side of the backplane, SPG-AVA-DMUX-C1
The backplane for the SPG-AVA-DMUX is labeled SPG-AVA-DMUX/-R. It is designed to be
fitted in a Flashlink rack unit and to take up a single slot. The connection side will face outward
on the back side of the Flashlink rack when mounted correctly. The table below is an overview
of the connectors and their associated functions.
