Hello @nishant00
To troubleshoot PSU issues on an ION 9000, you can first check the power supply status from the CLI by running the command dump sensor type=power summary, which provides information about PSU detection and health. Additionally, review the system to see if any alarms have been triggered related to the power supply and identify whether the issue corresponds to the left or right PSU. It is also important to physically check the LED status on the PSU, as abnormal or missing LEDs can indicate a problem. If no LEDs are illuminated and the sensor output or alarms suggest a fault, this typically indicates a hardware failure, and in such cases the PSU will need to be replaced by opening a support case.
