Alarms & troubleshooting

OPT_LOS (Optical Loss of Signal)
Port LINK/ACT LED off, MPU ALM LED solid red
Input optical power is below receiver sensitivity threshold due to broken fiber patch cord, remote transmitter disabled, or remote CFP2 failure.
1. Execute 'display transceiver verbose' via CLI to verify Rx optical power. 2. Measure input power at fiber connector using an optical power meter (-10.6 dBm to -4.3 dBm nominal). 3. Inspect and clean optical fiber connectors and CFP2 optical receptacles. 4. Verify that the remote port laser is administratively enabled. 5. Replace the fiber jumper or swap the CFP2 module if the fault persists.
TEM_HA (Optical Module High Temperature Alarm)
Port LINK/ACT LED solid amber, chassis fans ramp to 100%
Subrack air filter clogged, fan tray malfunction, elevated ambient data center temperature, or internal CFP2 component degradation causing internal temperature to exceed 70°C threshold.
1. Check equipment room HVAC to ensure ambient temperature is between 20°C and 26°C. 2. Execute 'display fan' to check fan tray operational status and RPM. 3. Clean or replace subrack air filters. 4. Ensure unobstructed airflow around the CFP2 slot. 5. If chassis airflow is normal but specific CFP2 remains overheated, replace the module.
BIAS_HA (Laser Bias Current High Alarm)
Port LINK/ACT LED solid amber
CFP2 internal LAN-WDM laser diode aging or driver circuit degradation causing the automatic power control (APC) to drive bias current beyond warning threshold.
1. Execute 'display transceiver verbose' to query the bias currents across all 4 optical lanes. 2. Compare values with the module specification threshold to confirm progressive degradation. 3. Check 'display interface' for output errors, link stability, and packet drops. 4. Schedule a maintenance window to hot-swap the degraded CFP2 module with a spare unit. 5. Dispatch failed module for RMA processing.
IN_PWR_LOW (Optical Rx Power Low Warning)
Port LINK/ACT LED slow blinking amber (0.5Hz)
Optical Rx power is near receiver sensitivity threshold (-10.6 dBm to -8.6 dBm) due to excessive link attenuation, microbending, contaminated ODF adapters, or splice degradation.
1. Run 'display transceiver verbose' to inspect individual Rx power across all 4 LAN-WDM lanes. 2. Inspect fiber patch cord routing; ensure bending radius exceeds 30mm. 3. Inspect with a fiberscope and clean LC connectors and ODF patch panels with dry lint-free wipes. 4. Perform OTDR testing along the 10km link to identify high-loss events or degraded splices. 5. Adjust optical attenuation or remediate degraded fiber segments.
CRC_EXC (Port Ethernet CRC Errors Excessive)
Port LINK/ACT LED alternating yellow and green
Optical signal degradation, low OSNR, connector contamination causing high bit error rate (BER), or poor contact/oxidation on the CFP2 104-pin host connector interface.
1. Execute 'display interface [interface-name]' to track input CRC/FCS error increment rates. 2. Verify Rx power stability to ensure no intermittent optical dips or marginal power levels. 3. Unseat the CFP2 module, inspect the 104-pin gold finger connector, and clean with electronic contact cleaner. 4. Re-seat CFP2 firmly into the cage and torque both jack screws. 5. If CRC errors continue, perform a cross-swap test to isolate between the port/slot and the CFP2 module, then replace the faulty module.
