Power.
But you have the
possibility to cut the power at the data line.
For this you open the case with the four
screws on both sides. Then you must set the jumper JP1 from ENA (Enable) to DIS
(Disable).
Furthermore, you also have the option of leaving power to the hub only when the hub
is connected to the Host PC and the Host PC is turned on. For this you have to set the
jumper JP2 to HOST. If JP2 is set to ON, then power is continuously applied to the
hub. See the following picture.
