Overview 1.2 OVERVIEW Cabletron Systems Fast Ethernet Switch Modules connect the ATX hub to a maximum of four individual Ethernet IEEE 802.3 Local Area Networks (LANs). Through the ATX backplane, connectivity to other Fast Ethernet devices, as well as connectivity to FDDI, Token Ring, and Ethernet networks is supported. You can configure the module to support Transparent Spanning Tree, Source Routing, or Source Routing Transparent Bridging on each of the FDDI, Token Ring, or Ethernet

Chapter 1: Introduction 1.3.1 Connectors The 3H02-04 includes four 8-pin RJ45 receptacle connectors that you can attach directly to the network by using unshielded twisted-pair (UTP) cabling. The ATX power supply provides the power for the module. An internal receive/transmit pair crossover is provided in the NOTE second connector on each port. This means that when either a station or server is directly attached to a 3H02-04 port, you can choose to use either straight-through or

3H08-04 FE Switch Module 1.4 3H08-04 FE SWITCH MODULE The 3H08-04 (Figure 1-3) provides connection for four independent 100BASE-FX LANs to the ATX backplane and packet processing engine (PPE). It includes processing circuitry for receiving and forwarding packets between the connected 100BASE-FX LANs within each module. The 3H08-04 contains several LEDs to indicate the module’s operational status. The 3H08-04 supports fiber optic and the IEEE 802.3 100BASE-FX specification. 1.4.1 C

CHAPTER 2 CONNECTING TO THE NETWORK This chapter provides reference material and instructions that network administrators can use to configure the Fast Ethernet Switch Modules. For instructions on adding a switch module to the ATX, see Chapter 5, Adding/Swapping Modules. 2.1 POWER-UP LED SEQUENCE Watch the LED sequence during power-up. It takes about 1 minute for the ATX to complete the power-up diagnostics. The ATX begins system diagnostics on the PPE (topmost module) and then indivi

Connecting to a Network 2.2.2 Connecting the 3H08-04 FE Switch Module You can connect each of the four pairs of ST fiber ports on the 3H08-04 to a 100BASE-FX port on a device such as a hub, using fiber optic cable. Each fiber segment has a pair of female ST connectors clearly marked as “RX” and “TX.” Attach the transmit (TX) connector on the 3H08-04 to the receive (RX) connector on the attached device. Similarly, you must then connect the receive (RX) connector on the 3H08-04 to the trans
