Note: If a port is to operate at 100 or 1000 Mbps, Category 5 cabling must be used.
Category 3 cabling does not meet 100 Mbps specifications. For 10 Mbps operation only,
Category 3 or Category 5 cabling can be used. Refer to the “100BASE-TX Network” on
page2-3 for information about 100BASE-TX networks and cabling.
Note: The fixed ports of the modules support Category 5 UTP cabling with an impedance
between 85 and 111ohms for 100 Mbps operation.
The modules are capable of operating at either 10, 100, or 1000 Mbps. The module
automatically senses the speed of the other device and adjusts its speed accordingly.
Note: The fixed ports of each module support Category 5 UTP cabling with an
impedance between 85 and 111 ohms for 100 and 1000 Mbps operation and can
automatically sense the port speed of the other device and adjusts its speed accordingly.
