Internal connections
As a general rule, all internal electrical and communications connections are made at the factory. How-
ever, if modules have to be moved, for example, and the connections therefore removed, you will have to
re-establish the connections between 1)
the Power Unit ASIC
and
the Driver Board(s)
on the one hand and
2) the Power Unit ASIC and
the Optical Cable Adapter Board
on the other.

Connections between Power Unit ASIC and Driver Boards
See the figures and tables on the following pages for the correct connection of internal electrical and
communications connections.
Note: The minimum optical cable bending radius is 50 mm.
