The following table shows the kind of activity that occurs in various LED
illumination combinations:
Reset Button
This button is used to reset the hub while it is powered on. This action clears
any temporary error conditions that may have occurred, restarts the hub and
executes the hub self test. A typical instance of where you might use the Reset
button is in the event of a hub malfunction or error condition.

Power Connector
The 10/100 hubs do not have a power switch; they are powered on when
connected to an active AC power source. The hubs automatically adjust to
various voltages (depending on the country) between 100-127 and 200-240
volts and either 50 or 60 Hz. There are no voltage range settings required.
