2 Locate the first point along the path at which power out of range or absent is observed, or
there is a significant difference between expected and observed power. This point is
referred to as the "First point of concern" in this procedure.
...................................................................................................................................................................................................
Examine the alarms close to the first point of concern.

...................................................................................................................................................................................................
4 Troubleshoot the alarms, concentrating on the points adjacent to the first point of concern.
The problem is most likely located between the first point of concern and the detection
point immediately upstream from it.
Note: It may take several seconds after corrective actions have been applied for
channel missing, channel absent, and power out of range alarms to clear.
1. Ensure that the relevant connection exists and is administratively up at the first point
of concern and at the point immediately upstream from it.
CLI
2. Examine the output for the connection of the appropriate band and channel. If the
connection exists then check the admin states of the connection and associated ports.
CLI
3. If the connection or ports are admin down then the entities must be brought admin up
in order to clear the alarm(s).
To bring a connection admin up:
CLI
If this does not resolve the problem, go to 4.
4. If this connection terminates on a transponder then confirm that the associated client
port is administratively up.
