Alarms & troubleshooting

OPT_LOS (Optical RX Loss of Signal)
Host port LINK/ACT LED is OFF
Remote laser disabled, fiber break, loose or contaminated LC connector, or optical path loss exceeding RX sensitivity threshold (<-14.4 dBm).
1. Run 'display transceiver interface verbose' to verify RX optical power. 2. Measure incoming power with an optical power meter to confirm range (-8.2 dBm to 0.5 dBm). 3. Clean LC connectors using an optical fiber cleaner pen and re-seat. 4. Use an OTDR to detect fiber cuts or high splice losses along the optical span. 5. If incoming optical power is verified normal, replace the local SFP+ transceiver.
TX_FAULT (Transmitter Laser Hardware Fault)
Host port LED shows steady Amber or OFF
Internal laser driver circuitry failure, damaged/blown laser diode, poor gold-finger pin contact, or unstable supply voltage to the SFP+ cage.
1. Unseat the module and inspect edge connector pins for physical damage, oxidation, or debris; clean if needed. 2. Reseat firmly into the cage and verify if the Tx Fault alarm clears. 3. Execute 'transceiver tx-disable' followed by 'undo transceiver tx-disable' to reset the laser driver. 4. Move the SFP+ module to an alternate verified port to rule out host cage hardware defects. 5. If the fault persists, replace the defective SFP+ module.
BIAS_HIGH_ALM (Laser Bias Current High Alarm)
Host chassis ALM/ERR LED blinks Amber slowly; port LINK LED remains steady Green
Aging and degradation of the 1310nm DFB laser chip; Auto Power Control (APC) increases bias current to maintain optical output, signaling imminent laser end-of-life.
1. Run 'display transceiver verbose interface' to check current Bias Current value against high-alarm threshold (typically 90-100 mA). 2. Inspect Tx Output Power to verify if optical power level is degrading. 3. Ensure link redundancy or reroute traffic to avoid unexpected network outage. 4. Schedule a maintenance window to proactively replace the degraded Huawei 10G SFP+ module.
TEMP_HIGH (Transceiver High Temperature Alarm)
Switch chassis FAN/ALM LED Amber or Red; port LINK LED remains steady Green
Data center ambient temperature out of spec (>35°C), clogged cabinet air filters, defective chassis cooling fans, or blocked airflow causing internal SFP+ temperature to exceed 75°C (or 85°C for industrial grade).
1. Run 'display transceiver verbose interface' to monitor real-time SFP+ operating temperature. 2. Verify host switch fan status ('display fan'), check for fan module failures, and remove dust filter blockages. 3. Inspect cold-aisle air supply and adjust precision HVAC setpoints to bring intake temperature to nominal levels. 4. If neighboring modules remain at normal temperatures, isolate and replace the internally defective, overheating SFP+ module.
RX_PWR_LOW (Optical RX Power Low / CRC Error Alarm)
Port LINK LED is steady Green or intermittently flickering Amber (packet loss/CRC errors)
Fiber micro-bend/macro-bend violation, contaminated or cracked optical patch panel bulkhead adapter, high splice insertion loss, or degraded patch cord driving RX power near sensitivity boundary (-11 dBm to -14 dBm).
1. Run 'display interface' to check if InErrors, CRC, or FCS counter increments continuously. 2. Run 'display transceiver verbose interface' to compare current Rx Power with lower warning/alarm thresholds. 3. Inspect patch cord routing in the rack and eliminate any tight micro-bends or pinched cables. 4. Inspect with a fiberscope and clean ODF bulkhead adapters and fiber patch cord ends. 5. Replace the patch cord; if the issue persists, dispatch cable teams to re-splice high-loss joints on the outside plant fiber.
