3Com Server manual 2Larger-Scale TR-in-FE System

1-2CHAPTER 1: INTRODUCTION

A larger-scale TR-in-FE configuration appears in Figure 1-2. Such a system allows both token ring and Ethernet devices to share the same Fast Ethernet physical wiring infrastructure and server base. Servers that are to be used for both token ring and Fast Ethernet clients must be equipped with both 3C395 and Fast Ethernet NICs.

The 3C395 NIC is based on 3Com Fast Ethernet technology. The NIC has the following features:

■Parallel Tasking architecture for high throughput and low processor utilization

■Support for full-duplex operation

■Support for PCI 2.0 or higher specifications

■32-bit bus master design

■Status LEDs

■Single shielded RJ-45 connector

■Support for Category 5 unshielded twisted-pair (UTP) cabling for 100BASE-TX Fast Ethernet networks
