Alarm Troubleshooting
LO-TXPOWER Alarm
Default Severity: Minor (MN), Non-Service-Affecting (NSA)
Logical Objects: PPM
The Equipment Low Transmit Power (LO-TXPOWER) alarm is an indicator of the transmitted optical signal
power of NCS 1002. This alarm occurs on the client optics controller when the measured individual lane
optical signal power of the transmitted signal falls below the default or user-defined threshold. This alarm
occurs on the trunk optics controller when the total optical signal power of the transmitted signal falls below
the default or user-defined threshold. You can configure the threshold value using the controller optics R/S/I/P
tx-low-threshold command in the config mode. The range is from -400 to 300 dBm (in units of 0.1 dBm).
Clear the LO-TXPOWER Alarm
Step 1
Verify the value of the low transmit power threshold of NCS 1002 using the show controller optics R/S/I/P command.
Step 2
If the value is not within the low transmit power threshold range, configure the low transmit power threshold using the
controller optics R/S/I/P tx-low-threshold command in the config mode. The range is from -400 to 300 dBm (in units
of 0.1 dBm).
Step 3
If the value is within the range of the low transmit power threshold, physically verify, by using a standard power meter
that the optical output power is overcoming the expected power threshold. If so, the pluggable module should be replaced
at first opportunity.
If the condition does not clear, log into the Technical Support Website at
for more information or call Cisco TAC (1 800 553-2447).
LOCAL-FAULT Alarm
Default Severity: Major (MJ), Service-Affecting (SA)
Logical Objects: Client
The LOCAL-FAULT alarm is raised on the NCS 1002 client port provisioned with 10 GE, 40 GE, or 100 GE
payloads. This alarm occurs when a local fault character sequence is received in the incoming MAC stream
as defined in IEEE 802.3.
Clear the LOCAL-FAULT Alarm
Verify that the NCS 1002 receives proper MAC streams from the far-end router or switch.
If the alarm does not get cleared, you need to report a Service-Affecting (SA) problem. Log into the Technical Support
