100BASE-TX/10BASE-T Pin Assignments
With 100BASE-TX/10BASE-T cable, pins 1 and 2 are used for
transmitting data, and pins 3 and 6 for receiving data.
Because 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 pinouts.
Note:
If auto-negotiation is disabled for an RJ-45 port, the auto-MDI/
MDI-X pin signal configuration is also disabled.
