When the optical power switching threshold has been set up, the module will
automatically compare the monitored optical input power in channel A and
channel B with the optical input power switching threshold. If the optical
input power in either channel A or channel B is out of the threshold, it will
issue an alarm. The table below lists auto switching status under different
conditions in the auto mode (1 stands for alarm; 0 stands for normal).
