See the chapter titled "Running the Dell Diagnostics" in your Diagnostics and Troubleshooting Guide for detailed instructions. Your computer's NIC connector (an RJ45 connector located on the back panel; see Figure 5-1) 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 an Ethernet UTP concentrator or hub, depending on your network configuration. Observe the following cabling restrictions for 10BASE-T and 100BASE-TX networks: For 10-megabit (Mb) operation, use Category 3, 4, or 5 wiring and connectors. For 100-Mb operation, use Category 5 wiring and connectors. Voice and data lines should be in separate sheaths. The maximum cable run length (from a workstation to a concentrator) is 100 meters (m) (328 feet [(ft]). The maximum number of workstations (not counting concentrators) on a network is 1024. The maximum number of daisy-chained concentrators on one network segment is four. This section provides instructions for configuring the computer's integrated, 10/100-megabits-per-second (Mbps) 3Com NIC under the following operating systems: Microsoft Windows NT 4.0 Microsoft Windows 95 NOTE: If you reinstall Windows NT 4.0, you must install Service Pack 3 and the bus-mastering EIDE device driver before you can install the NIC drivers.
