Chapter 2: Network Requirements

2.210BASE-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.

2.3100BASE-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.

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.

2.4100BASE-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.
