2.6 Ethernet Ports
RJ-45 Ports
RJ-45 Ports (Auto MDI/MDIX)
: The RJ-45 ports are auto-sensing for 10Base-T, 100Base-
TX, or 1000Base-T connections. Auto MDI means that the switch can connect to another
switch or workstation without changing the straight-through or crossover cabling. See the
figures below for straight-through and crossover cabling schematics.

Note:
The
“+” and “-” signs represent the polarity of the wires that make up each wire pair.
All ports on this industrial Ethernet switch support automatic MDI operations. Users can use
straight-through cables (see figure below) for all network connections to PCs, servers, and
other switches or hubs. With straight-through cabling, pins 1, 2, 3, and 6 are at one end of
the cable and are connected straight through to pins 1, 2, 3 and 6 at the other end of the
cable. The table below (
Table 2.4
) shows the 10BASE-T/100BASE-TX/1000BASE-T MDI
