Ports

RJ-45 ports (Auto MDI/MDIX): The RJ-45 ports are auto-sensing for 10Base-T, 100Base-TX or 1000Base-T 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.

￿RJ-45 Pin Assignments

Pin Number	Assignment
1	Tx+
2	Tx-
3	Rx+
6	Rx-

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 10BASE-T/100BASE-TX/1000BASE-T MDI and MDI-X port pin
	outs are as tabled below.
