About Your Computer 27
•A yellow network activity light flashes when the computer is
transmitting or receiving network data. (A high volume of network
traffic may make this light appear to be in a steady "on" state.)
•A dual-colored network link and speed light, which is green when a
good connection exists between a 10-Mbps network and the computer,
or is orange when a good connection exists between a 100-Mbps
network and the computer. When the light is off, the computer is not
detecting a physical connection to the network.
The network controller includes a Remote Wake Up feature. For more
information, see "Network Operations" and "Power Management."
NOTICE: Do not connect a modem cable to the network adapter. Voltage
from telephone communications can damage the network ada pter.
Network Connection Requirements
Press one end of the UTP Ethernet cable into the network adapter on your
computer until the cable snaps securely into place. Connect the other end
to an RJ45 jack wall plate or to an RJ45 port on a UTP concentrator or hub,
depending on your network configuration.
Dell recommends the use of Category 5 wiring and connectors for our
customers' networks.
NOTE: Verify the type of network device to which you are connecting the
computer. A hub typically operates at 10-Mbps. A switch can o perate at 10- or
100-Mbps. Ensure that the network adapter is configured for the appropriate
speed. See network adapter diagnostics and configuration utility on Dell
Diagnostics.
