RASFinder User Guide
Front Panel
The front panel contains three groups of LEDs that provide the status of the LAN connection, link
activity, and general status of the RASFinder. The EtherNet LAN LEDs display the activity of the LAN
in whether the RASFinder is connected to the LAN, transmitting or receiving packets, and if a
collision is in progress. The Link LEDs display the status of the three links that can be connected to
the RASFinder with whether a link is ready to transmit or receive serial data. The last group of LEDs
indicates whether the self test passed or failed and if the power ON/OFF switch on the back of the
RASFinder is set to ON.
