Table 19 lists the pin signal definitions when a port is operating in the MDI
configuration at 10 or 100 Mbps.

Table 19. MDI Pin Signals - 10 or 100 Mbps

Table 20 lists the pin signal definitions when a port is operating in the
MDI-X configuration at 10 or 100 Mbps.

Table 20. MDI-X Pin Signals - 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
MDI/MDI-X setting defaults to the MDI-X setting.
