Cisco Systems 694 Benutzerhandbuch

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.

Damaged data in CMOS can cause undetermined problems.

Damaged data in BIOS code can cause undetermined problems.

Ethernet link status 
LED does not work.

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.

The Ethernet activity 
LED does not work.

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.

Data is incorrect or 
sporadic.

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).

The Ethernet 
controller stopped 
working without 
apparent cause.

Check the following: 

Try a different connector on the switch.

If you suspect the adapter is faulty, contact the Cisco Technical Assistance 
Center (TAC).
