All the Fast Ethernet ports automatically detect the signal from the connected devices
to negotiate the link speed and duplex mode. Auto MDI/MDIX allows you to connect
another switch, hub, or workstation without changing straight-through or crossover
cables. Crossover cables cross-connect the transmit lines at each end to the received
lines at the opposite end.

Straight-Through Cabling Schematic
The Ethernet cables use Pins 1, 2, 3, and 6 of an 8-pin RJ45 connector. The signals of
these pins are converted by the automatic MDIX function, as shown in the following
table:
Connect one side of an Ethernet cable into any switch port and connect the other side
to your attached device. The wiring cable types and maximum cable length are as
follows.
Uplink ports: 10BASE-T: 2-pair UTP/STP Category 3, 4, 5 cable, EIA/TIA-568
