ABOUT THIS GUIDE About This Guide provides an overview of this guide, describes guide conventions, and tells you where to look for specific information. This guide describes how to install, configure, and troubleshoot the 3Com® Fast EtherLink® XL PCI 10/100BASE-TX network interface card (NIC). This NIC is called the 3C905B-TX NIC in this guide. If the information in the README.
2 ABOUT THIS GUIDE Conventions Table 1 and Table 2 list conventions that are used throughout this guide.
1 INTRODUCTION The 3Com® 3C905B-TX network interface card (NIC) provides a high-performance connection to an Ethernet or Fast Ethernet network. This NIC operates at 100 Mbps or 10 Mbps automatically, depending on the speed of the connected hub. TX DATA ACT 10 L 100 N K Figure 1-1 3C905B-TX NIC There are two types of 3C905B-TX NICs: the 3C905B-TX NIC and the 3C905B-TX-NM NIC.
1-2 CHAPTER 1: INTRODUCTION Unless specifically indicated, the name 3C905B-TX is used throughout this guide to refer to both NICs. This chapter describes the 3C905B-TX NIC features and PC and server requirements.
Remote Wake-up 1-3 Remote Wake-up Remote Wake-Up support is enabled for the 3C905B-TX NIC. If you are using the 3C905B-TX NIC in a PC that supports Remote Wake-Up through the PCI bus, the 3Com NIC receives wake-up signals and wakes the PC from a sleep state. Installation and Configuration The 3Com NIC Diagnostics program allows you to test the 3C905B-TX NIC, configure it, and display the NIC configuration information. If you are running DOS, you cannot use this program.
1-4 CHAPTER 1: INTRODUCTION Make sure that you are running the latest BIOS for your PC or server, even if your PC is new. Contact your PC manufacturer for more information. How Do I Install the 3C905B-TX NIC? To complete installation, install the NIC in your PC or server, connect it to the network, and install the network driver. The installations steps are depicted in Figure 1-2.
2 INSTALLING THE NIC There are two types of 3C905B-TX NICs: the 3C905B-TX NIC and the 3C905B-TX-NM NIC. They are both installed in your PC and connected to the network in exactly the same way. After you connect the 3C905B-TX NIC to the network, you connect the Remote Wake-Up cable to the motherboard. Before you begin, make sure that you also have the user guide and the 3C905B-TX EtherDisk diskettes, and that your PC meets the requirements described in Chapter 1.
2-2 CHAPTER 2: INSTALLING THE NIC 7 Insert the 3C905B-TX NIC into an empty PCI slot, shown in Figure 2-1. Make sure that the NIC is firmly seated in the slot. Screw 3C905B-TX NIC PCI slot Figure 2-1 Inserting the NIC 8 Secure the NIC with the screw you removed earlier. If you are installing the Remote Wake-Up connector, go to “Connecting the Remote Wake-up Cable” at the end of the chapter before replacing the PC cover. 9 Replace the PC cover and reconnect all previously connected cables.
Connecting to the Network 2-3 Connecting to the Network You must connect the NIC to the network before installing the network driver. To connect the 3C905B-TX NIC to the network cable, follow these steps: 1 Connect the network cable to the RJ-45 port on the 3C905B-TX NIC, as shown in Figure 2-2. TX RJ-45 port Data ACT 10 NL 100 K RJ-45 connector LEDs Figure 2-2 Connecting the Network Cable to the RJ-45 Port 2 Connect the other end of the network cable to a 10BASE-T or a 100BASE-TX network port.
2-4 CHAPTER 2: INSTALLING THE NIC Connecting the Remote Wake-up Cable WARNING: Install the NIC in slot 1 in the PC (as described earlier) before plugging in the 3-pin connector. Only properly trained and authorized personnel should perform service. Contact your PC manufacturer for information about safe service techniques. 1 Insert the cable into the connector on the NIC, shown in Figure 2-3. Twist the cable twice before attaching the cable to the motherboard.

Crossover Cable Troubleshooting Tips 4-13 Crossover Cable Troubleshooting Tips When you work with network cabling, concentrators, and NICs from different vendors, it is possible to connect everything and still have no communication between file servers and workstations. When there are several unknown variables, it is difficult to determine which component is broken. Use these tips to isolate the problem. 1 Determine whether your equipment complies with the 10BASE-T or 100BASE-TX standard.
4-14 CHAPTER 4: TROUBLESHOOTING Using wires from opposing pairs can cause signals to be lost. For a 100BASE-TX cable, pins #1 and #2, and #3 and #6 must be on the same twisted strand. Troubleshooting Hubs with Crossover Cable When there is doubt whether a hub is performing correctly, or if the impedance settings are in question, a crossover cable can help you isolate the failing component.
Frequently Asked Questions 4-15 Frequently Asked Questions Table 4-2 describes some common questions and answers about the 3C905B-TX NIC. Table 4-2 Frequently Asked Questions Question Answer Which PCI slot is best for my PCI NIC? 3Com PCI NICs are designed to work in any bus mastering PCI slot, preferably slot 1. Avoid any PCI slot next to an ISA slot. This is often a shared slot and does not support bus mastering.The NICs perform best in those slots that support bus mastering data transfers.
