Troubleshooting the Ethernet Controller
This section provides troubleshooting information for problems that might occur
with the 10/100/1000-Mbps Ethernet controller.
This section contains the following topics:
• Network Connection Problems, page 5-4
• Ethernet Controller Troubleshooting Chart, page 5-5
Network Connection Problems
If the Ethernet controller cannot connect to the network, check the following
conditions:
• Make sure that the cable is installed correctly.
The network cable must be securely attached at all connections. If the cable

If you set the Ethernet controller to operate at either 100 Mbps or 1000 Mbps,
you must use Category 5 or higher cabling.
• Determine whether the switch or device to which the WAVE appliance is
connected supports autonegotiation. If it does not, try configuring the
integrated Ethernet controller manually to match the speed and duplex mode
of the switch.
• Check the Ethernet controller LEDs on the device back panel. (See
Figure 1-2.)
These LEDs indicate whether a problem exists with the connector, cable,
or
