receiving data.
RJ-45 Pin Assignments
Pin Number
"+" and "-" signs represent the polarity of the wires that make up each wire pair.
Note:
All ports on this switch support automatic MDI/MDI-X operation, you can use straight-through cables 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.
