* PSU status LED on the front panel on 15000 / 23000 appliance is lit in amber.

* Alert status LED on the front panel on 15000 / 23000 appliance is blinking red.

* LOM WebUI - *Appliance Health* page might show:

  * all Voltages - 0.00 Volt
  * Case fan units - 0 RPM
  * Temperatures - 0 � C / 85 � C / 100 � C

  *Example* :

* In some configurations (where one of the Power Supply Units is not plugged to a power outlet), */var/log/messages* file repeatedly shows:  

  `xpand[`*PID*`]: [ERR] i2c_smbus_read_byte_data STATUS_WORD 0x2848`

* Reboot resolves the issue only temporarily.

* The issue occurs after completing the Gaia OS First Time Configuration Wizard.

## Cause

Software driver collision causing appliance Hardware Health monitoring to report false zero sensor readings, regardless of actual sensors status.

Note: Symptoms are scoped to Hardware Health monitoring services and have no other effect on appliance functionality.
