2. After the clear alarm is generated, check that the alarm indicator on the
service board is still blinking red.
3. Check alarm information.

is failed, the optical module receive power is too low)
Because no services exist, after the interface that generates such an alarm is shut down, the alarm indicator becomes off.
The receive optical power of the interface that generates such an alarm exceeds the lower limit.
Shut down the interface that generates such an alarm as a workaround of the problem.
Check whether the low receive optical power issue is caused by a line or module fault. If so, rectify the line or module fault.
