Ports
RJ-45 ports (Auto MDI/MDIX)
: The RJ-45 ports are auto-sensing for 10Base-T or
100Base-TX devices connections. Auto MDI/MDIX means that you can connect to
another switch or workstation without changing straight through or crossover
cabling. See figures as below for straight through and crossover cable schematic.

Note
“+” and “-” signs represent the polarity of the wires that make up
each wire pair.
All ports on this industrial switch support automatic MDI/MDI-X operation, you can
use straight-through cables (See Figure below) for all network connections to PCs
or servers, or to other switches or hubs. In straight-through cable, pins 1, 2, 3, and
6, at one end of the cable, are connected straight through to pins 1, 2, 3 and 6 at
the other end of the cable. The table below shows the 10BASE-T/ 100BASE-TX
MDI and MDI-X port pin outs.
