100Base-Tx Network - Cabletron Systems DLE52-MA User Manual

Chapter 2 Network Requirements
If a port is to operate at 100 Mbps, Category 5 cabling must be
used. For 10 Mbps operation only, Category 3 cabling can be
used. Refer to Section 2.3 for information about 100BASE-TX
networks and cabling.

100BASE-TX NETWORK

The fixed ports of the DLE02-MA and the DLE52-MA provide an RJ45
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 Cabletron Systems Cabling Guide for details.
The fixed ports of the DLE02-MA and the DLE52-MA support
Category 5 UTP cabling with an impedance between 85 and
111 ohms for 10 and 100 Mbps operation.
The DLE02-MA and the DLE52-MA are capable of operating at
either 10 or 100 Mbps. The DLE02-MA and the DLE52-MA
automatically sense the speed of the other device and adjusts
its speed accordingly.
