Ethernet Controller
Problem
Ethernet link status
LED does not work.
The Ethernet activity
LED does not work.
Data is incorrect or sporadic.
The Ethernet controller stopped working without apparent cause.
Actions
Check the following:
• Make sure that the switch to which the WAVE appliance is connected is powered on.
•
•
Check all connections at the Ethernet controller and the switch.
Use another port on the switch.
• If the switch does not support autonegotiation, manually configure the
Ethernet controller to match the switch.
(Both sides of the connection must be set the same. Mixing autonegotiation and hard-coded configurations will result in half duplex, which causes a CRC error on the interface.)
• If you manually configured duplex mode, make sure that you also manually configure the speed.
Check the following:
• The network might be idle. Try sending data from this appliance.
•
•
Check all connections at the Ethernet controller and the switch.
Use another port on the switch.
Check the following:
• Make sure that you are using Category 5 or higher cabling when operating the appliance at 100 Mbps or 1000 Mbps.
•
•
Make sure that the cables do not run close to noise-inducing sources such as fluorescent lights.
Make sure the RJ-45 jack is securely latched (avoid cables with broken latches).
Check the following:
•
•
Try a different connector on the switch.
If you suspect the adapter is faulty, contact the Cisco Technical Assistance
Center (TAC).
Undetermined Problems
Use the information in this section if the diagnostic tests did not identify the failure, the devices list is incorrect, or the system is inoperative.
