Connecting to a Network To connect your system to and configure it for use on an Ethernet network, you must complete the following steps: 1. Connect the network cable to the back of your computer. See the following subsection, "Network Cable Requirements," for detailed instructions. 2. Verify that the NIC is enabled in the System Setup program. See "NIC" in Chapter 2 for instructions. 3. Configure the NIC, and install the network drivers by running the 3Com Install program. See "Configuring the NIC" found later in this chapter for detailed instructions. 4. Run the Network Interface Test Group in the diskette-based diagnostics to verify that the NIC is operating properly. See the chapter titled "Running the Diskette-Based Diagnostics" in your Diagnostics and Troubleshooting Guide for detailed instructions. Network Cable Requirements Your computer's NIC connector (an RJ45 connector located on the back panel; see Figure 4-1) is designed for attaching an unshielded twisted pair (UTP) Ethernet cable. Press one end of the UTP cable into the NIC connector until the cable snaps securely into place. Connect the other end of the cable to an RJ45 jack wall plate or to an RJ45 port on a UTP concentrator or hub, depending on your network configuration. Observe the following cabling restrictions for 10Base-T and 100BaseTX networks: • For 10-megabit (Mb) operation, use Category 3 or greater wiring and connectors. For 100-Mb operation, use Category 5 wiring and connections. Voice and data lines should be in separate sheaths. • The maximum cable run length (from a workstation to a concentrator) is 328 feet (ft) (100 meters [m]). • The maximum number of workstations (not counting concentrators) on a network is 1024. • The maximum number of daisy-chained concentra- tors on one network segment is four. Configuring the NIC To configure the NIC, you must first use the Dell DiskMaker to make a NIC driver diskette from the diskette image installed on your hard-disk drive. The Dell DiskMaker is located in the Dell Accessories program group or folder. For instructions on using Dell DiskMaker, see the online help provided in the program. After you have made a NIC driver diskette, see the appropriate subsection found later in this chapter for your particular network environment. Client Drivers for Novell NetWare Environments You can configure your system as a client computer under Novell NetWare running any of the following operating systems: • Microsoft Windows 95 • Microsoft Windows NT 3.5x • Microsoft Windows for Workgroups • Microsoft Windows 3.x • MS-DOS • IBM OS/2 NOTE: The drivers for Windows NT 4.0 are provided on the Windows NT CD in the \drvlib\netcard\x86\3c90x and \i386\drvlib.nic\3c90x directories. Microsoft Windows 95 Client Driver Install the Microsoft Windows 95 client driver as follows: 1. Connect the integrated NIC to its network according to the instructions in "Connecting to a Network" found earlier in this chapter. 2. Start Windows 95. 3. If you are prompted to insert a diskette containing the network drivers, skip to step 11. Otherwise, continue to step 4. Using Integrated Devices 4-3
