Table 9 lists the cabling specifications for the 10/100/1000Base-T twisted
pair ports.
Note
The auto-MDI/MDI-X feature on the twisted pair ports automatically
configures the MDI/MDI-X setting when a link is established with an
end node. Available when a port is at the default setting of Auto-
Negotiation, this feature allows you to use a straight-through twisted
pair cable when connecting any type of network device to a port.
Disabling Auto-Negotiation on a port and setting the speed and
duplex mode manually also disables the auto-MDI/MDI-X feature. A
port where Auto-Negotiation has been disabled defaults to MDI-X.
Disabling Auto-Negotiation may require manually configuring a
port’s MDI/MDI-X setting or using a crossover cable.
