Responding to Errors
Overview The following information describes how to respond to errors on the
140 NOE 771 x0.
Detecting Errors When faults occur, the NOE 771 xx LED display can help you determine what went
wrong. The following figure shows the pattern that the LEDs should display during
normal operation.
The Run indicator will be solid. The Coll (collision) LED may flash, indicating that
collisions are occurring on the Ethernet network. Such collisions are normal.
If a fault occurs, the normal LEDs may be extinguished or other indicators may light.
This topic discusses errors reported by the Active, Ready, Coll, Link, Kernel, Appl
and Fault indicators.
For each type of error, try the suggested remedies in the order given. If no remedy
suggested here overcomes the error, call your local service representative or call
Schneider Electric customer service at 1-800-468-5342 for further directions.
