5802 Board Renumber
Board renumber took place.
If the system is functioning
properly, simply remove the error
from the Transient Error Log. If the
system is not functioning properly,
check the Transient Error Log to
verify that a board renumber took
place. Then compare the system’s
previous configuration to the one
after board renumbering to
determine if the board renumber
caused logical IDs to shift.
