Alarms & troubleshooting

ETH_LOS (Ethernet Optical RX Loss of Signal)
RUN/ALM LED solid red, corresponding port LINK LED off
Fiber break or tight bend radius; dirty/damaged optical connector; remote peer optical transmitter failure; faulty SFP receiver
1. Inspect fiber connection and clean end-faces using an optical cleaning pen. 2. Measure optical RX power with an optical power meter against receiver sensitivity specs. 3. Verify peer TX optical output and patch cord continuity. 4. If peer and link are nominal, hot-swap and replace the local GE SFP transceiver.
OPT_BIAS_HIGH (Laser Bias Current High Degradation)
RUN/ALM LED blinks red or amber slowly (0.5Hz)
Internal laser diode (LD) aging within SFP module; drive circuit component drift; prolonged high-temperature operation causing component degradation
1. Log into OLT CLI and execute display port ddm-information to check bias current and alarm thresholds. 2. Inspect subrack airflow and slot operating temperature. 3. During a maintenance window, hot-swap the degraded SFP transceiver with an authentic Huawei spare. 4. Re-run DDM query to confirm bias current returns to normal baseline.
OPT_TEMP_HIGH (SFP Operating Temperature High)
RUN/ALM LED solid yellow/amber or blinking amber
OLT chassis fan tray failure or reduced RPM; equipment room ambient exceeds specs (>55°C); clogged dust filter restricting airflow; defective SFP internal thermistor/high power draw
1. Check chassis fan tray status (display fan) and verify normal fan speeds. 2. Clean dust filters at subrack air intake vents. 3. Verify equipment room HVAC/air conditioning operates within 20°C-25°C range. 4. If a single SFP port reports over-temperature while others are normal, replace that specific SFP transceiver.
ETH_CRC_OVER (Ethernet Port CRC Errors Exceeded)
Port LINK LED solid green, ACT data LED flashing yellow rapidly
RX optical power hovering near sensitivity limit; contaminated optical ferrule or micro-fracture; oxidation on SFP gold-finger contacts; duplex mismatch or faulty shielding on copper SFP
1. Run display port statistics to monitor incoming CRC error increments. 2. Clean optical connectors and ensure at least 3dB margin above RX receiver sensitivity. 3. Unseat SFP transceiver, check PCB contacts for oxidation, and re-seat firmly. 4. If using copper SFP modules, inspect patch cable and match duplex/speed negotiations on both peers. 5. Replace the patch cord and SFP transceiver to eliminate error growth.
BD_STATUS_FAIL (Board Hardware Fault / Comm Loss)
RUN/ALM LED solid red, all port LEDs off
Backplane connector bent pins or poor contact; onboard DC-DC power converter failure; control bus communication failure with active control board; FPGA/PHY ASIC self-test failure
1. Run display board command on OLT to check if H801EG8E status is 'Failed' or 'Offline'. 2. Eject the H801EG8E board, carefully inspect backplane connector pins for bends, and clear any debris. 3. Re-align with card guide rails, push firmly into the slot, and tighten ejector screws. 4. If the alarm persists with a solid red LED, test the board in an alternate known-good slot. 5. If the fault follows the board, declare H801EG8E hardware failure and replace with a spare unit.
