Out-of-Band Troubleshooting

For the Ethernet or Token-Ring telemetry interface, if the Activity LED is off, verify that the probe is properly connected to the telemetry network and that there is traffic on the network. Also, verify that you have the correct Physical Connector selected from the Modify/View Interface Values menu.

If the ~ Line On or Power LED is off, verify that power is properly connected to the probe and to the correct power source.

If the Fault LED is on, the probe failed the self-test.Repeat the installation procedures and verification of installation. If you have an option installed, you can look at each port’s Fault LED to see which port is generating the fault condition.

For the Token-Ring telemetry interface, if you are still having difficulty, call your local Agilent service representative. For the Ethernet telemetry interface, continue with the following “Ethernet Telemetry Interface” section.

Ethernet Telemetry Interface

If you selected Auto Negotiate for the Link Speed parameter, verify that the connected Hub or switch supports this mode of operation. If you are not sure, configure the link speed and full-duplex or half-duplex manually.

If you manually selected the Link Speed, be careful to configure it correctly. If you configure the Link Speed for 100 MB/s and you connect the probe to a 10MB/s network, the probe will generate 100% utilization for that segment.

If you manually selected the link speed, verify that you are using the correct speed. Also, if you manually selected the link speed, verify that you are using the correct mode of operation (full-duplex or half-duplex). 10MB/s Ethernet is always half-duplex.

If you are still having difficulty, call your local Agilent service representative.
