Alarms & troubleshooting

CPRI_LOS (CPRI Optical Interface Loss of Signal)
ALM LED steady red, OPT1/OPT2 LED off or blinking red
Optical fiber broken or bent beyond minimum radius between BBU and RRU, contaminated LC connector, or remote SFP laser disabled/damaged
1. Inspect OPT1/OPT2 outdoor waterproof connector sealing and optical fiber bending radius. 2. Measure downlink optical Rx power using an optical power meter to confirm it falls within the nominal -14 dBm to -1 dBm range. 3. Clean the LC connector end-faces and SFP ceramic ferrule with an optical cleaning pen. 4. Check the BBU baseband port TX status via LMT/OMC, and replace the SFP module if optical power remains below threshold.
OPT_PWR_LOW (SFP Low Optical Receive Power Alarm)
ALM LED slow blinking yellow or red, OPT LED blinking green
Excessive optical path insertion loss, dirty connector end-face, high fusion splice loss, or remote SFP transmitter laser aging
1. Query SFP Digital Diagnostic Monitoring (DDM) data via OMC to check real-time Rx power and threshold values. 2. Use an OTDR to detect high-attenuation bend points, damaged patch panels, or degraded splices. 3. Clean all optical LC mating surfaces and recheck if Rx power rises above -12 dBm. 4. If the opposite Tx output power is abnormally degraded, replace the BBU-side optical transceiver.
SFP_TEMP_HIGH (SFP Transceiver Over-Temperature Alarm)
ALM LED steady or slow blinking yellow, RUN LED steady green
RRU chassis heatsink blocked or under intense solar radiation, ambient temperature exceeding +55°C, or deployment of non-industrial grade (commercial 0-70°C) SFP transceivers
1. Verify the installed SFP module model to ensure it meets the industrial temperature grade requirement (-40°C to +85°C). 2. Clear dust, debris, and foreign matter from the R8862 cooling fins to restore convective airflow. 3. Install an RRU solar sunshade shield if the unit is mounted in direct unshaded sunlight. 4. If internal DDM temperature remains above 85°C, replace the transceiver with a ZTE-certified industrial SFP module.
CPRI_BER_EXC (CPRI Bit Error Rate Exceeded / Sync Loss)
ALM LED blinking yellow, OPT LED intermittently flashing yellow or green
CPRI rate negotiation mismatch (e.g. 2.4576G vs 9.8304G), optical dispersion/wavelength drift, or micro-cracks in optical fiber causing severe phase jitter
1. Verify CPRI line rate parameters and link topology configuration between BBU and RRU in OMC. 2. Confirm that transceivers on both sides share the same optical wavelength (e.g., 1310 nm single-mode) and nominal rate capability. 3. Check optical patch cables for structural pinching, mechanical strain, or micro-bending. 4. If CPRI frame error counters continue incrementing, replace the SFP modules as a matched pair.
SFP_FAULT (SFP Transceiver Hardware / I2C Bus Fault)
ALM LED steady red, OPT LED steady off
SFP edge connector oxidation/damage, internal EEPROM/MCU firmware crash, I2C bus lockup, or insertion of an unsupported/non-genuine transceiver
1. Eject the SFP module from the R8862 slot and inspect the golden finger contacts for scratches, corrosion, or contamination. 2. Clean the module gold fingers and the internal cage pins using an isopropyl alcohol cleaning swab. 3. Reseat the SFP firmly until latched, then trigger an optical port reset via the management system. 4. If transceiver inventory information and DDM registers remain unreadable, replace with a genuine ZTE-qualified industrial module.
