Connections
Eight 10/100 Mbit ports (eight-pin R45 sockets) on the ConneXium 499NES18100
allow eight DTE or other independent network segments complying with the
standards IEEE 802.3 100BASE-TX / 10BASE-T to be connected. These ports
support autopolarity.
The socket casings are electrically connected to the front panel of the switch
module.The pin configuration complies with MDI-X:
pins 3 and 6 provide one line pair
pins 1 and 2 provide another line pair
remaining pins are not used
