What does it indicate when the LED on a 13G power supply blinks green 5 times and then goes off?

When the LED on a 13G power supply blinks green 5 times and then goes off, it signifies a PSU mismatch. This blinking pattern typically indicates that the power supply being used does not match the specifications required by the server or system. In a proper configuration, power supply units should be of the same type, wattage, and firmware version to ensure compatibility and reliable operation.

If there is a mismatch, the system is unable to properly utilize the power supply, which is crucial for maintaining the integrity and performance of the server. Therefore, noting this blinking pattern is essential for diagnosing and addressing power supply issues effectively. Recognizing and rectifying a PSU mismatch is important to avoid system instability or power-related failures.
