Note: If a port is to operate at 100Mbps, Category 5 cabling must be used. Category 3
cabling does not meet 100 Mbps specifications. For 10 Mbps operation only, Category3
or Category 5 cabling can be used. Refer to “100BASE-TX Network” on page 2-2 for
information about 100BASE-TX networks and cabling.
Note: The fixed ports of the module support Category 5 UTP cabling with an impedance
between 85 and 111ohms for 100 Mbps operation. The module is capable of operating at
10, 100, or 1000 Mbps and can automatically sense the port speed of the other device and
adjust its speed accordingly.
