Alarms & troubleshooting

INV_FAULT (Inverter Fault / Transfer to Bypass)
Fault LED solid Red, Bypass LED solid Amber, Inverter LED off, continuous audible alarm
Inverter bridge IGBT drive abnormal, DC bus short circuit, internal hardware overcurrent protection trip, or inverter voltage feedback loop failure
1. Check the LCD event log to record active fault codes and DC bus voltage levels. 2. Verify that bypass supply is stable; do not power off unit abruptly to prevent load drop. 3. Disconnect non-critical branch circuits and inspect downstream distribution for short circuits. 4. If loads and bus voltage are verified normal yet fault persists, transfer to maintenance bypass and replace the power/inverter board.
OUTPUT_OVERLOAD (Output Overload Alarm)
Fault/Alarm LED flashes Amber or solid Red, 100% load bar indicator lit, buzzer beeps twice per second
Connected IT equipment exceeds 3kVA/3kW rated capacity, high downstream inrush current, or resistive earth leakage on output cabling
1. Immediately check real-time load percentage and output phase currents on the LCD menu. 2. Shed non-essential auxiliary server racks and peripheral equipment. 3. Monitor the overload countdown timer to prevent transfer to bypass or forced shutdown. 4. Rebalance PDU branch circuit loads and evaluate upgrading to a larger capacity power system.
BATT_EOD_WARN (Battery Undervoltage / EOD Warning)
Battery LED flashes Amber, Fault LED solid Amber/Red, buzzer beeps once per second (continuous tone near EOD)
Prolonged mains outage depleting battery string to cut-off threshold, external battery pack breaker tripped, or aged high-impedance cells
1. Check AC input utility breaker and initiate standby generator startup if mains restoration is delayed. 2. Inspect external battery cabinet DC circuit breaker and power cabling connections. 3. Initiate graceful automated shutdown scripts for connected hypervisors and storage arrays. 4. When AC mains recovers, verify bulk charging current; perform battery conductance/internal resistance test if charge fails.
OVER_TEMP_FLT (Internal Overtemperature Fault)
Fault LED solid Red, Inverter LED blinking or off, Bypass LED lit, continuous acoustic warning
Ambient telecom room temperature exceeds 40°C, air intake dust filters clogged, blocked airflow path, or cooling fan speed degradation
1. Check server room CRAC/air conditioning operation and ensure ambient intake temp is reduced below 25°C. 2. Inspect front air intake bezel and rear exhaust area; remove any blocking items and clean dust accumulation. 3. Check internal heatsink temperature sensors (NTC) readings via the LCD maintenance menu. 4. If the alarm persists after heatsinks cool down, inspect temperature sensor wiring and thermal interface material.
FAN_FAULT (Cooling Fan Speed Abnormal / Fan Fault)
Alarm LED flashes Amber, Run LED solid Green, buzzer beeps once every 2 seconds
Rear DC fan bearing seized by foreign objects, tachometer feedback wire disconnected, or fan driver power rail failure
1. Visually and acoustically inspect rear chassis fans to identify the stalled or vibrating unit. 2. Under safe maintenance isolation, clear any loose wiring or physical debris obstructing the blades. 3. Verify that the 4-pin fan harness is firmly seated on the controller PCB and check PWM feedback. 4. If control supply is present but rotation is missing or out of spec, replace the OEM DC fan module.
