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
port pin outs.

The following figures show the cabling schematics for straight-through and crossover.
2.6 Cabling
Use the four twisted-pair, category 5e, or the above cabling for the RJ-45 port connections. The cable
between the switch and the link partner (switch, hub, workstation, etc.) must be less than 100 meters
(328 ft.) in length.
The small form-factor pluggable (SFP) is a compact optical transceiver used in optical communications for
both telecommunication and data communication applications.
