Alarms & troubleshooting

VSWR_ALARM / RF_REFLECT_HIGH
RF Alarm Red LED solid, downlink transmit power automatically derated
Antenna feeder VSWR exceeds threshold (>1.5), connector moisture ingress, or jumper damaged
1. Measure return loss and VSWR on the feeder line with an antenna analyzer;\n2. Inspect tower-top RF connectors for water ingress or loose threads;\n3. Re-torque RF connectors to specification (25-30 N·m) and re-seal with 1+3 tape;\n4. Replace damaged coaxial jumpers or surge arrestors and re-verify VSWR.
CPRI_OPTICAL_FAIL / LINK_DOWN
OPT Port Amber LED solid, baseband digital link disconnected
SFP+ transceiver failed, fiber jumper pinched/broken, or optical Rx power below threshold (<-15dBm)
1. Measure optical Rx power at the fiber connector with an optical power meter;\n2. Clean SFP+ ferrule and fiber end-faces with a specialized optical cleaner;\n3. Verify fiber routing bend radius exceeds minimum threshold;\n4. Replace SFP+ transceiver with a genuine industrial wide-temp 10G module.
OVERTEMP_PROTECT / PA_SHUTDOWN
ALM Red LED solid, power amplifier protected and shut down
Chassis heatsink fins obstructed, or excessive solar radiation with ambient >+55°C
1. Clear debris, bird nests, and accumulated dirt from chassis heatsink fins;\n2. Verify the solar radiation shield is intact and properly secured;\n3. Adjust carrier output power or enable intelligent sleep energy-saving modes;\n4. Power amplifier automatically resumes once internal temperature normalizes.
