UltraMobilePC
Network Hub or
Switch
Network cable with RJ-45
connectors
Example of the UltraMobilePC connected to a Network Hub or Switch for use with the
built-in Ethernet controller.
Network Connection
Connect a network cable, with RJ-45 connectors on each end, to the modem/network port on the
UltraMobilePC 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 UltraMobilePC but requires connection to a net-
work switching hub with “duplex” enabled. The software default is to use the fastest setting so no
user-intervention is required.
Twisted-Pair Cable
The 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 not compatible with RJ-11 telephone
connectors. If connecting two computers together without a hub in between,
a crossover LAN cable is required (Fast-Ethernet model). (Gigabit models
support auto-crossover so a crossover LAN cable is optional.)
1000BASE-T (or Gigabit) is only supported on selected models.
