6E122-26, 6E132-25, 6E123-26 and 6E133-25 User’s Guide

2.2

10BASE-T NETWORK

When connecting a 10BASE-T segment to any of the 6E12X-26 and
6E13X-25 ports (Interfaces 1 through 24), 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 6E12X-26, with an FE-100TX installed in ports 25 and 26, provides
an RJ45 connection that supports Category 5 UTP cabling with an
impedance between 85 and 111 ohms. 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.

2.4

100BASE-FX FIBER OPTIC NETWORK

Ports 25 and 26 of the 6E12X-26 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.

NOTE

The 6E12X-26 with an FE-100TX installed is capable of
operating at either 10 or 100 Mbps. The FE-100TX can
automatically sense the speed of the other device and adjusts
its speed accordingly.
