1
Determine the transponder line port that is connected to OT VA port, MVAC port, or
SVAC port.
CLI show interface topology <shelf slot port>
show interface <shelf slot port>
WEBUI Select Connections > Physical Topology.
This indicates the expected power, actual power, and what each OT or SVAC port is
connected to.
If the optical line to which the alarmed interface connects is Manual power managed,
enter (CLI)
show interface powermgmt sh/sl/[Line|Lineout]
If the Power Management Type is Manual, verify that the output power target set for the
encoder interface is consistent with the output power required by the Engineering
Planning Tool plan for the network. If necessary correct the target output power for the
interface and wait 5 minutes to see if the alarm clears.

2
Visually inspect the fiber connecting the transponder (OT) line port and OT VA, MVAC
or SVAC port. Check that the fiber is not being pinched or bent tightly. Ensure that the
fiber connectors are properly seated at the OT line out port or SVAC In, MVAC In, VA In
port, and any bulkhead connectors (if any) between them.

3
Using an optical power meter, measure the optical output power of the transponder to
ensure that the output power is within specification. Make this measurement as close as
possible to the output port of the transponder.
If... Then...
the output power is within the acceptable
limits,
continue with Step 5.
the
output power is not within acceptable
limits,
the transponder port may be dirty. Clean and
inspect port, and measure the optical output
power of the transponder. Continue with Step
4.
