The Actively LED is designed to provide visual feedback regarding the status of data transmission. When this LED flashes, it indicates that there is active data flowing through the device, such as a switch or router. This behavior is expected in networking devices during normal operation, as the flashing LED corresponds to the transfer of packets of data.
In contrast, other scenarios such as an improper cable connection or device malfunction typically would not result in a flashing LED; instead, they might cause the LED to remain off or show a steady light, indicating no data transfer is occurring. A power interruption would lead to the device losing power entirely, which would also cause the LED to turn off. Therefore, the active data transmission is the primary reason the Actively LED would be flashing, confirming that the device is functioning correctly and is engaged in communication over the network.
