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 is attached but the
problem remains, try a different 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 appliance back panel. (See Figure 1-2.)
These LEDs indicate whether a problem exists with the connector, cable, or switch:
–
The Ethernet link status LED is on when the Ethernet controller receives a link pulse from the
switch. If the LED is off, there might be a defective connector or cable or a problem with the
switch.
–
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 switch and network are
operating and that the correct device drivers are installed.
