Network Connector Indicators
The network connector on the C/Dock Expansion Station
has the following indicators (see Figure 1-13):

link integrity indicator activity indicator
Figure 1-13. Network Connector Indicators
A green link integrity indicator lights up when there
is a good connection between the network and the
network connector on the C/Dock Expansion Sta­
tion. When the green indicator is off, the computer is
not detecting a physical connection to the network.
When the green light blinks, the network cable has
reversed polarity and you should use another cable.
A yellow activity indicator flashes when the system
is transmitting or receiving network data. (A high
volume of network traffic may make this indicator
appear to be in a steady “on” state.)
The Dell Diagnostics that came with your Dell Latitude
computer includes tests that help you troubleshoot the
controllers in your C/Dock Expansion Station.
The subtests in the Network Interface test group of the
Dell Diagnostics verify the basic operation of the net­
work controller in the C/Dock Expansion Station. They
test the controller’s internal functions, including read and
write access to its registers and internal transmit and
receive (loopback) capability.
The subtests in the Serial/Infrared Ports test group check
the C/Dock Expansion Station’s interface with external
devices (such as a serial mouse or a printer). The subtests in
this test group are not intended as a diagnostic test for the
external device itself.
The subtests in the USB test group check the C/Dock
Expansion Station’s interface with external devices (such
as a mouse). The subtests in this test group are not
intended as a diagnostic test for the external device itself.
For complete instructions on using the Dell Diagnostics,
see Chapter 4, “Running the Dell Diagnostics,” in the
Reference and Troubleshooting Guide that accompanied
your computer.
