When you connect the Micro USB-B port, it becomes the primary connection and, while connected, all messages are sent to the
Micro USB-B port.
1.
Power on the PC.
2.
Connect the USB-A end of cable into an available USB port on the PC.
3.
Connect the MicroUSB-B end of cable into the MicroUSB-B console port on the S4048-ON.
4.
Power on the S4048-ON.
5.
Install the necessary USB device drivers.
6.
