Fast Ethernet Ports
Prepare the M12, 4-pole D-Coded Fast Ethernet Port mating cable for Ethernet
connection. The M-12 D-coded Fast Ethernet ports are auto-sensing for 10Base-T or
100Base-TX devices connections. Auto MDI/MDIX means that you can connect to
another switch or workstation without changing straight through or crossover cabling.
