Note
The twisted pair ports on the switch feature auto-MDI when
operating at 10, 100, or 1000 Mbps. A port is configured as MDI or
MDIX when it is connected to an end node. Consequently, you can
use a straight-through twisted pair cable when connecting any type
of network device to a port on the switch.
