The terminations of the Channels have been set to ON by default, because it is assumed that the new segment

Termination LEDs
Fig. 15 - Termination Switches
The termination LED of the corresponding Channel is activated when the termination switch is set to ON.
When the DB9 connector is used and the cable starts at the ProfiHub, it is recommended to use the
termination on the DB9 plug and NOT the ProfiHub. This way, the connector can be removed while
maintaining termination on the bus.
