51Using the Notebook PC 4Network Hub or SwitchNetwork cable withRJ-45 connectorsThis is an example of the Notebook PC connected to a NetworkHub or Switch for use with the built-in Ethernet controller.Network Connection (Gigabit Support)Connect a network cable, with RJ-45 connectors on each end, to the modem/network port on the Note-book PC and the other end to a hub or switch. For 100 BASE-TX / 1000 BASE-T speeds, your networkcable must be category 5 or better (not category 3) with twisted-pair wiring. If you plan on running theinterface at 100/1000Mbps, it must be connected to a 100 BASE-TX / 1000 BASE-T hub (not a BASE-T4 hub). For 10Base-T, use category 3, 4, or 5 twisted-pair wiring. 10/100 Mbps Full-Duplex is sup-ported on this Notebook PC but requires connection to a network switching hub with “duplex” enabled.The software default is to use the fastest setting so no user-intervention is required.Twisted-Pair CableThe cable used to connect the Ethernet card to a host (generally a Hub or Switch) is called a straight-through Twisted Pair Ethernet (TPE). The end connectors are called RJ-45 connectors, which are notcompatible with RJ-11 telephone connectors. If connecting two computers together without a hub inbetween, auto-crossover is supported on this Notebook PC so a crossover LAN cable is not required.
