Table 12 lists the pin signals when a port is operating in the MDI
configuration at 10 or 100 Mbps.
Table 13 lists the pin signals when a port is operating in the MDI-X
configuration at 10 or 100 Mbps.
The MDI/MDI-X setting is established automatically when a port is set to
Auto-Negotiation. If a port’s speed and duplex are set manually, the setting
defaults to the MDI-X setting.
