This is applicable to ROBEN-3 expansion units (ROBEN-3TX, ROBEN-3TS and ROBEN-3TM).

End-user / customer should not use the ON/OFF button on the power supply unit. Leave it on and don’t touch it. Use Thunderbolt cable / cord to power down and power up the ROBEN-3 unit:

  • To Power Down: disconnect or unplug the thunderbolt cable or cord from the mac computer or from the ROBEN-3 expansion unit.
  • To Power Up: connect or plug in the thunderbolt cable or cord to computer or ROBEN-3 expansion unit.

Our intent is to have customers leave the power supply switch alone.
