This topic describes how to make the power cable, ground cable, and network cable.
A.2.1 Making Console-Ethernet Integrated Cables

and a network port at the same time. Therefore, a console-Ethernet integrated cable is needed
to support the concurrent use of the serial port. The console-Ethernet integrated cable is a type
of non-standard cable, which must be made on site as required.
