2-2 Network Requirements

2.3 100BASE-TX NETWORK

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 de vices to opera te at 100Mbps. 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 accordin gly.
