Note: If a port is to operate at 100 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 “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 111 ohms 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.
Note: The fixed ports of the module support Category 5 UTP cabling with an impedance between
85 and 111 ohms for 100 and 1000 Mbps operation.
Front-panel ports 1 through 30 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.
