10/100BASE-TX Pin
Assignments
All 100BASE-TX RJ-45 ports support automatic MDI/MDI-X operation, so you can
use straight-through or crossover cables for all network connections to PCs,
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.

1000BASE-TPin
Assignments
All 1000BASE-T ports support automatic MDI/MDI-X operation, so you can use
straight-through cables for all network connections to PCs, servers, or switches.
The table below shows the 1000BASE-T MDI and MDI-X port pinouts. These ports
require that all four pairs of wires be connected. Note that for 1000BASE-T
operation, all four pairs of wires are used for both transmit and receive.
