Installation

If the Activity LED is off, verify that LanProbe is properly connected to the 
network and that there is traffic on the network.

If the ~ Line On or Power LED is off, verify that power is properly connected to 
LanProbe 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 are still having difficulty, call your local Agilent service representative.
