Integrated NIC Connector
Your system has two integrated 10/100–megabit-per-second (Mbps) NIC. The NIC provides all the functions of a separate
network expansion card and supports both the 10BASE-T and 100BASE-TX Ethernet standards.
Network Cable Requirements
Your system's RJ-45 NIC connector is designed for attaching an unshielded twisted pair (UTP) Ethernet cable equipped
with standard RJ-45-compatible plugs. Press one end of the UTP cable into the NIC connector until the plug snaps
securely into place. Connect the other end of the cable to an RJ-45 jack wall plate or an RJ-45 port on a UTP concentrator
or hub, depending on your network configuration. Observe the following cabling restrictions for 10BASE-T and 100BASE-
TX networks.
NOTICE:
To avoid line interference, voice and data lines must be in separate sheaths.
For 10BASE-T networks, use Category 5 or greater wiring and connectors.
For 100BASE-TX networks, use Category 5 or greater wiring and connectors.
The maximum cable run length from a workstation to a concentrator is 328 ft (100 m).
For 10BASE-T networks, the maximum number of daisy-chained concentrators on one network segment is four.
