Chapter 1 BayStack 380 Switch 43
Using the BayStack 380 10/100/1000 Switch
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.
For more information about autosensing and autonegotiation modes, see
Chapter 4, “Troubleshooting,” on page 171.
