 If the SystemPowerGood signal has not asserted by the time the VR Watchdog Timer expires, the FW powers down the system,

logs a SEL entry, and emits a beep code (1-5-1-2). This failure is termed as VR Watchdog Timeout.

4.2.1 Voltage Regulator Watchdog Timer Sensor – Next Steps

1. Ensure that all the connectors from the power supply are well seated.

2. Cross test the baseboard. If the issue remains with the baseboard, replace the baseboard.

4.3 Power Unit

The power unit monitors the power state of the system and logs the state changes in the SEL.

4.3.1 Power Unit Status Sensor

The power unit status sensor monitors the power state of the system and logs state changes. Expected power-on events such as DC

ON/OFF is logged and unexpected events are also logged, such as AC loss and power good loss.
