Troubleshooting the Ethernet Controller
These LEDs indicate whether a problem exists with the connector, cable,
or hub.
–
The Ethernet activity LED is on when the Ethernet controller sends or
receives data over the Ethernet network. If the Ethernet activity LED is
off, make sure that the hub and network are operating and that the correct
device drivers are installed.
–
The Ethernet link status LED is on when the Ethernet controller receives
a link pulse from the hub. If the LED is off, there might be a defective
connector or cable or a problem with the hub.
•Make sure that you are using the correct device drivers that are supplied with
your device.
•Check for operating system-specific causes for the problem.
•Make sure that the device drivers on the client and the device are using the
same protocol.
•Test the Ethernet controller.
The method used to test the Ethernet controller depends on which operating
system you are using (see the Ethernet controller device driver README
files).
