Network Cable Requirements
Your computer's NIC connector (an RJ45 connector located on the back panel) 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 100BASE-TX networks.
CAUTION: To avoid line interference, voice and data lines must be in separate sheaths.
For 10BASE-T networks, use Category 3 or greater wiring and connectors.
For 100BASE-TX networks, use Category 5 wiring and connectors.
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.
For 10BASE-T networks, the maximum number of daisy-chained concentrators on one network segment is four.
Configuring the NIC
This subsection provides instructions for configuring or reconfiguring the computer's integrated NIC under the following operating
systems:
Microsoft Windows NT
Microsoft Windows 95
Microsoft Windows for Workgroups
MS-DOS

automatically detected and installed. Instructions for reconfiguring the NIC driver are included in the following
subsections.
