Condition
The system error LED and Power Supply Unit (PSU) alert on the front panel might stay lit even if the
power supplies are operating normally and there are no errors in the System Event logs. In this
scenario, the issue is cosmetic and does not affect power supply or system functionality.
Cause
False PSU alert errors are a known issue with Lenovo BMC firmware prior to version 20.00.
Solution
1. Check the LED on the rear of the PSU when a system error LED and PSU alert is shown on
the front panel.
• If the LED on the PSU is green or blinking green, the errors and alerts are false and the
PSU is indicating a good state.
• If the LED on the PSU is amber, the errors and alerts are valid and the PSU might be
failing and require a replacement.
2. Go to the Lenovo support website and search for keywords BMC update Web GUI.
3. Select the BMC Update utility for Web GUI that is applicable to your ThinkServer model.
4. Verify that the update version shown is version 20.00 or higher. Download both of the update
files (the .tgz update utility and the readme).
