Synology DiskStation Flashing Blue Light

The flashing blue light on your Synology DiskStation is a visual cue, indicating the device’s specific state or condition. In the context of a power failure, light typically signifies that the DiskStation is booting up or undergoing a system check. Understanding this signal is crucial for effective troubleshooting.

Possible Causes for the Issue

Power Interruption: A sudden power failure or interruption is the most common trigger for a flashing blue light. When power is restored, the DiskStation goes through a boot-up sequence, and the flashing blue light is part of this process.

Firmware or Software Issues:  Outdated or corrupted system files can lead to abnormal startup behavior. In such cases, the DiskStation may get stuck in a loop, causing the blue light to flash repeatedly.
