The ODU Power Feeder

The ODU Power Feeder is used to provide power (-48 VDC) to AU-ODU-HP High
Power ODUs. It transfers transparently all signals between the AU-IDU and the
ODU, while injecting DC power received from an external source. Each ODU
Power Feeder unit can serve up to four High Power ODUs. Up to three ODU Power
Feeder units can be installed in a 1U high Power Feeder panel.
