Alarms & troubleshooting

RX_LOS (Loss of Optical Input Signal)
Port LINK LED Off, System ALM LED Solid Red
No optical power received. Causes include remote TX disabled, broken/bent patch cord, dirty LC connector, or peer optic failure.
1. Run 'show interface optical-transceiver' via CLI to verify if RX power is below the -15.8 dBm sensitivity threshold. 2. Verify the remote peer interface is enabled and TX is emitting. 3. Inspect and clean optical connectors and transceivers with a fiber scope and one-click cleaner. 4. Measure physical optical line power with an optical power meter to rule out cable rupture or excessive attenuation. 5. Replace the SFP+ module if the physical fiber link verifies normal.
TX_FAULT_BIAS (Laser Bias Current High / Transmitter Fault)
Port LINK LED Blinking Red or Off, System ALM LED Solid Amber/Red
Internal DFB laser degradation over time causing APC to overdrive bias current beyond high warning threshold, or internal driver/circuit fault triggering hardware TX Fault.
1. Execute 'show interface optical-transceiver detail' to retrieve DDM stats for TX Bias Current and TX Output Power. 2. If TX Bias Current exceeds 70mA while TX power drops below -8.2 dBm, the laser is degraded. 3. Execute 'shutdown' followed by 'no shutdown' on the interface to reset the optical driver. 4. If the condition persists and link drops, replace the SFP+ 10km optical transceiver immediately.
TEMP_HIGH (SFP+ Module Operating High Temperature Alarm)
Chassis FAN speed ramps to 100%, System ALM LED Solid Amber
Transceiver internal temperature exceeded the 75°C threshold due to high ambient room temperature, clogged air filters, airflow blockage, or chassis fan failure.
1. Check room precision cooling and verify cold aisle temperature is maintained between 20°C and 25°C. 2. Verify chassis fan operation via 'show environment fan' and replace faulty fan trays. 3. Clean rack air filters and clear obstructions around intake and exhaust vents. 4. If only one module is overheating in a cool chassis, swap the module to verify if its internal power converter is defective.
CRC_ERR_FLAP (Port Link Flapping & CRC Error Threshold Exceeded)
Port LINK LED Intermittently Toggling Green and Off, ACT LED Irregular Blink
RX optical power hovering near critical sensitivity threshold (-13 dBm to -15 dBm), scratched/contaminated fiber endface, or physical fiber stress causing excessive bit errors and link drops.
1. Execute 'show interface <port>' to verify if Input errors, CRC, and framing errors are incrementing. 2. Check DDM optical power graphs to verify if RX power fluctuates around the threshold. 3. Clean the patch cord ferrules using a dry cassette cleaner and replace the optical coupler/adapter if necessary. 4. Swap with a known-good patch cord to eliminate micro-bending or damaged fiber jumpers. 5. Adjust carrier-delay damping timers if needed and check the remote SFP+ transmitter stability.
RX_PWR_LOW (Optical RX Power Below Warning/Alarm Threshold)
Port LINK LED Solid Green, System ALM LED Solid Amber
Optical RX power has fallen below the DDM Low Alarm/Warning limit (-14.4 dBm to -15.8 dBm). Caused by span attenuation, optical patch panel loss, or weak transmitter at the remote end.
1. Run 'show interface optical-transceiver detail' to check current RX Optical Power against DDM thresholds. 2. Perform an OTDR test on the physical optical fiber to identify high-loss splices or macro-bends. 3. Clean all patch panel (ODF) mating sleeves and replace suspect interconnect jumpers. 4. If outside plant fiber loss is normal but remote TX power is low, replace the remote SFP+ module. 5. If the link length exceeds 10km, upgrade the optics to 40km (ER) or 80km (ZR) specifications.
