Alarms & troubleshooting

RX_LOS (Optical Receive Loss of Signal)
Port LINK/ACT LED OFF, System ALM LED solid Red
Fiber link break, remote optical transmitter disabled/failed, contaminated or damaged LC connector, macro-bending exceeding minimum radius
1. Execute CLI command 'show interface transceiver detail' to verify Rx optical power is below sensitivity threshold (-14.4 dBm); 2. Use an optical power meter to check remote Tx power and link attenuation across ODF panels; 3. Clean LC connectors using a dry optical cleaner and reseat; use OTDR to pinpoint fiber break if optical continuity is lost.
TX_FAULT (Transmitter Hardware Fault / Bias Current Alarm)
Port LINK/ACT LED blinking Red, System ALM LED solid Amber/Red
1310nm DFB laser diode degradation/failure, driver circuit supply voltage abnormal, laser bias current exceeding high alarm threshold, internal APC loop failure
1. Inspect DDM parameters via CLI to verify if Tx Bias Current exceeds high alarm limit (e.g., >80mA); 2. Toggle port administrative state via 'shutdown' followed by 'undo shutdown' to reset transmitter driver IC; 3. Check host cage 3.3V supply rails; if the condition persists, replace the industrial SFP+ transceiver.
DDM_TEMP_HIGH (SFP+ Module High Temperature Alarm)
System ALM LED solid Amber, Port LED remains Green with status alert
Outdoor telecom cabinet thermal control failure exceeding industrial limit (>85°C), fan tray failure or dust filter blockage, poor chassis airflow channel
1. Read real-time DDM temperature to confirm if reading exceeds the industrial rating (-40°C to +85°C); 2. Check chassis fan tray RPM speed and clean blocked air filters; 3. Verify outdoor cabinet TEC cooling or heat exchanger operation, and optimize airflow clearance around the chassis.
RX_PWR_LOW (Optical Receive Power Low Alarm)
Port LINK/ACT LED solid Amber or slow blinking Amber, System ALM solid Amber
Excessive link insertion loss over 15km path, contaminated or scratched LC ferrule endface, high splice loss along the span, degraded transmitter power at remote node
1. Query Rx optical power via DDM and compare with thresholds (Warning ~ -12 dBm, Alarm -14.4 dBm); 2. Clean all local and ODF optical connectors, and inspect ceramic alignment sleeves for cracks; 3. Check remote node Tx output power; use OTDR to detect and repair high-attenuation splice points.
LINK_FLAP_CRC (Link Flapping & Excessive CRC Errors)
Port LINK LED rapid alternating Green/Amber flashing, ACT LED erratic
Optical receive power fluctuating near the sensitivity limit causing frame check errors, poor edge-connector contact in SFP+ cage, loose LC latch, severe EMI interference
1. Execute 'show interface counters errors' to monitor the increment rate of CRC/FCS and Input errors; 2. Verify transceiver latch engagement in the cage; re-seat and inspect gold finger contacts for contamination or oxidation; 3. Replace the patch cord; if error accumulation continues while optical power is nominal, replace the SFP+ module.
