Network Connection Problems

OL-15012-02
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 WAE 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 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.
Make sure that you are using the correct device drivers that are supplied with
•
your device and that the device drivers on the client and the device are using
the same protocol.
Check for operating system-specific causes for the problem.
•
Test the Ethernet controller.
•
The method used to test the Ethernet controller depends on which operating
system that you are using (see the Ethernet controller device driver README
files).
