The fixed front panel ports of the module provide a connection that supports Category 5 UTP
cabling. The device at the other end of the twisted pair segment must meet IEEE 802.3u
100BASE-TX Fast Ethernet network requirements for the devices to operate at 100 Mbps. Refer to
the Cabling Guide for details.
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 either 10 or 100 Mbps. The module automatically
senses the speed of the other device and adjusts its speed accordingly.
