Alarms & troubleshooting

050201 (ECPRI_PORT_DOWN / 25GE eCPRI High-Speed Optical Link Failure)
Corresponding 25GE optical port LED flashing red; 5G Massive MIMO AAU transmission ceases
Fronthaul fiber chromatic dispersion/loss over-budget, 25G SFP28 wavelength unlock, or WDM mux attenuation
1. Run CLI diagnostic to check eCPRI link status and PCS lane synchronization error counters; 2. Verify colored SFP28 transceiver optical channel matches passive WDM mux port wavelength exactly; 3. Replace with industrial-grade 25G eCPRI transceiver and clean optical connector ferrules with lint-free dry tape.
050205 (ASIC_TEMP_OVERLIMIT / 5G Baseband ASIC High Thermal Shutdown Protection)
Board ALM LED solid red; board power automatically severed; V9200 chassis fans roar at 100% full speed
Full-load 300MHz carrier aggregation pushes ASIC past 80W; choked air filter or failed fan tray triggers safety trip (>95°C)
1. Pull out and wash/clean V9200 front air intake dust filter to restore unobstructed air intake; 2. Query fan tray health: `SHOW FAN`, hot-swap degraded fan modules failing to reach rated RPM; 3. Direct cold aisle HVAC airflow onto BBU cabinet; re-power and reset board once thermal sensors drop below 50°C.
050208 (CARRIER_POWER_UNBALANCE / 5G Carrier Aggregation Power Tilt)
Board ACT LED green, but OSS KPI reports reveal severe throughput throttling on specific component carriers
Baseband algorithm array weighting uncalibrated for RF cable phase delta, degrading MIMO beamforming gain
1. Trigger auto antenna calibration routine: `START ANTENNA CALIBRATION` to check amplitude/phase tracking; 2. Verify RF feeder jumpers between AAU and array are strictly phase-matched (length delta < 5mm); 3. Reload baseband beamforming parameter profile from EMS to eliminate inter-carrier interference.
