LNX-C800G Series User Manual V1.0

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 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 port pin outs.
The following figures show the cabling schematics for straight-through and crossover cables.
2.6 Cabling
◼
Twisted-pair segments can be connected with an unshielded twisted pair (UTP) or shielded
twisted pair (STP) cable. The cable must comply with the IEEE 802.3u 1000Base TX standard
(e.g. Category 5, 5e, 6, or 6a). The cable between the equipment and the link partner (switch,
hub, workstation, etc.) must be less than 100 meters (328 ft.) long.
Note:
The
“+” and “-” signs represent the polarity of the wires that make up each wire pair.
