 RJ-45 ports

There are 8x 10/100Mbps auto-sensing electrical ports for 10Base-T or 100Base-TX

devices connection. The UTP ports will auto-sense for either 10Base-T or 100Base-TX

connections. Auto MDI/MDIX means that another switch or workstation may be

connected without changing straight through or crossover cabling. See the below figures

for straight through and the crossover cable schematic.

[NOTE] “+” and “-” signs represent the polarity of the wires that make up each wire pair.

All ports on this 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.
