I
f power is provided through both the Ethernet and the PWR connectors, Ethernet power
takes precedence.
This allows the connection of a back-up battery to the ODU PWR
connector. The battery will only be used in case of an outage of the power over Ethernet.
The current power source (PWR or Ethernet connector), and the voltage at the PWR
connector are reported in the
