Interface Definition
10/100/1000Base-TX ethernet interface:
This switch provides MDI/MDI-X self-identification with cable support
on all 10/100/1000Basc-TX ports. In use, the Ethernet port of the
switch can be connected with other Ethernet terminal devices through
network cables (direct or cross).Please use Class 5 shielded twisted
pair. The Ethernet port pin definition is shown in the following figure:
RJ45 port supports automatic MDI/MDI-X operation, you can use a
straight line to connect to the PC or server, connect to other switches
or hubs. In the through line (MDI), pins 1, 2, 3, 4, 5, 6, 7, 8 correspond
to the connection; For the MDI-X port of a switch or hub, cross lines
are used: 1
