MAINTENANCE

ERROR MESSAGES

Error messages, along with the alarm indicators, are the most likely
indicators that an error has occurred in the system. When a maintenance
object fails periodic testing, the system automatically generates an error
record. The error record (log) is accessible through the SAT. The following
table lists and describes error messages that can be displayed on the SAT.
The table also includes possible solutions for some of the errors that are
encountered.
If the recommended solution includes CP replacement and, if repeated
replacement of hardware does not fix problems or similar problems seem to
be happening at many locations, suspect software problems. Contact the
Local FAST if this problem persists.
When the procedure indicates CP replacement, inspect each CP for the
following:
Bent pins
Damaged components (ICs, resistors, etc.)
Correct firmware vintage (call local FAST for assistance).
After the inspection is complete, reseat the circuit pack and if the problem
persists, replace the circuit pack. When returning a defective board to MLO,
include the associated Error Log entries on the trouble ticket.
