Avaya CM avEntFanFlt Fan Alarm

Jeremy Boilard

Problem Statement

An Avaya Communication Manager (Core) system reports a Major GW_ENV Server alarm with maintenance object avEntFanFlt and equipment reference similar to Fan 1 Sensor. This indicates the system detected a fan-related environmental fault on the gateway/server hardware.

Impact

A fan fault can reduce cooling capacity and may lead to overheating, hardware instability, or service impact if the condition persists. If the alarm clears quickly, it may have been transient, but the device should still be monitored for recurrence.

Troubleshooting Steps

  1. Confirm the active alarm details in the monitoring platform or Avaya management interface, including severity, maintenance object avEntFanFlt, alarm code, and affected fan sensor/equipment number.
  2. Check whether a corresponding clear event has already been received. Record the active duration if available.
  3. If the alarm has cleared, monitor the device for recurrence and review recent environmental or power events that may have affected the hardware.
  4. If the alarm remains active or reoccurs, check the physical chassis/server for fan status indicators, abnormal fan noise, blocked airflow, dust buildup, or elevated ambient temperature.
  5. Verify that all fan modules are fully seated and that airflow paths are unobstructed. Follow site hardware procedures before reseating or replacing any module.
  6. Review Avaya Communication Manager/server hardware logs for related GW_ENV, thermal, power, or fan sensor events.
  7. If a specific fan sensor continues to report failure, engage the appropriate field support or hardware maintenance process to inspect and replace the affected fan module.
  8. After corrective action, confirm that the avEntFanFlt alarm clears and that no related environmental alarms remain active.

Resolution

In the referenced scenario, the Major avEntFanFlt alarm cleared automatically after a short active period. No further action was required beyond confirming the clear event and monitoring for recurrence. For persistent or recurring alarms, inspect airflow and fan hardware, then replace the affected fan module as needed through the standard hardware support process.
