Chapter 2: Network Requirements
2.2

10BASE-T NETWORK

When connecting a 10BASE-T segment to any of the 6E123-50 and
6E133-49 ports (ENET 1 through 4), ensure that the network meets the
Ethernet network requirements of the IEEE 802.3 standard for
10BASE-T. Refer to the Cabletron Systems Cabling Guide for details.
2.3

100BASE-TX NETWORK

The 6E123-50, with an FE-100TX installed in ports 5 or 6, provides an
RJ45 connection that supports 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 6E123-50 with an FE-100TX installed is capable of
NOTE
operating at either 10 or 100 Mbps. The FE-100TX
automatically senses the speed of the other device and adjusts
its speed accordingly.
2.4

100BASE-FX FIBER OPTIC NETWORK

Ports 5 and 6 of the 6E123-50 support the Cabletron Systems FE-100FX
and FE-100F3 fiber optic interface modules. The device at the other end
of the fiber optic segment must meet the 100BASE-FX Fast Ethernet
network requirements to operate at 100 Mbps. Refer to the Cabletron
Systems Cabling Guide for details.
Multimode Mode Fiber Optic Cable Length
The maximum multimode fiber optic cable length of a 100BASE-FX
segment is covered in the Cabletron Systems Cabling Guide.
Single Mode Fiber Cable Lengths
The maximum single mode fiber optic length of a 100BASE-FX segment
may be no more than 5 km between Data Terminal Equipment (DTE to
DTE) in half duplex mode or 20 km (DTE to DTE) in full duplex mode.
