For 1000BASE-T, all 8 pins are used for four pairs of bi-directional data.
Table 3
lists the types of bi-directional data for each of the 1000BASE-T pin connectors.

Auto-polarity
The BayStack 380 Switch features auto-polarity. With autonegotiation enabled, auto-polarity
automatically reverses the polarity of a pair of pins from positive to negative or negative to
positive. This corrects the polarity of the received data if the port detects that the polarity of the
data has been reversed due to a wiring error.
