Standard USB
lower A supply

Each lower portion of the PoweredUSB port provides +5V @ 500mA. If more than 500mA are drawn
from a port, that port goes into USB over current, the +5 volts is turned off, and the condition is
reported to the host according to USB 2.0 specifications.

The listed maximum currents depend on the selected power supply. The +12V PoweredUSB ports
are protected with active over current circuits. If an over current condition occurs, unplug the DC
connection, remove the overcurrent condition, and re-cycle the DC connection to the Hub by
unplugging it, and then plugging it in again.
