Connections
Network Connection
Connect a network cable, with RJ-45 connectors on each end, to the
modem/network port on the Notebook PC and the other end to a
hub or switch. For 100 BASE-TX / 1000 BASE-T speeds, your network
cable must be category 5 or better (not category 3) with twisted-pair
wiring. If you plan on running the interface 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 supported 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.
1000BASE-T (or Gigabit) is only supported on selected models.
