Chapter 1: Introduction

1.36H122-08 OVERVIEW

The 6H122-08 is a Fast Ethernet interface module for Cabletron Systems 6C105 chassis that has six RJ45 switched ports and two optional Fast Ethernet Interface Module ports (100BASE-TX and 100BASE-FX) that provide Twisted Pair, Multimode, and Single Mode Fiber Optic cabling connectivity.

The 6H122-08 is used to connect individual high-bandwidth user devices, such as workstations, and provide a central switching point for multiple 10/100 Mbps Fast Ethernet segments.

1.3.1Auto-Negotiation

Twisted Pair ports on the 6H122-08 module have the ability to auto-negotiate the type of connection required to provide a link to another device. During Auto-Negotiation, two devices automatically exchange information “telling” each other what their operating capabilities are. The Auto-Negotiation feature targets the maximum capabilities that can be reached between the two devices. For example, the 6H122-08 adjusts to 100 Mbps when the device on the other end of the connection can also adjust between 10 Mbps or 100 Mbps. If the device on the other end of the connection can only operate at 10 Mbps, then the 6H122-08 adjusts to 10 Mbps operation.

When Auto-Negotiation is supported at both ends of a link, the two devices dynamically adjust to full or half duplex operation based on the maximum capability that can be reached between the two devices. If the device connected to the 6H122-08 cannot auto-negotiate, the 6H122-08 interface operates according to the capabilities of the other device.

1.3.2Connectivity

The 6H122-08 connects to Ethernet networks or workstations through six RJ45 ports on the front panel. These ports support Category 5 Unshielded Twisted Pair cables with an impedance between 85 and 111 ohms. These ports are IEEE 802.3u 100BASE-TX compliant.

The 6H122-08 has two front panel slots (ports 7 and 8) for optional Fast Ethernet Interface Modules (FE-100TX, FE-100FX, and FE-100F3) to support an uplink to 100 Mbps Ethernet backbones or a high speed connection to a local server using Twisted Pair, Multimode or Single Mode Fiber Optic cabling.
