When the port mode LED indicates a malfunction, which color would it typically show?

When the port mode LED indicates a malfunction, it typically shows amber. This color serves as a warning signal indicating that the port is experiencing issues that may prevent it from functioning properly. The amber light might be triggered by various problems, such as a hardware failure, misconfiguration, or a connection issue with the network device.

The use of amber as an indicator is consistent across many networking devices, as it typically conveys a state of caution, prompting network technicians to investigate further. In contrast, a green light usually signifies that the port is operating normally, while an off state might indicate that the port is disabled or not receiving power. The specific use of amber allows technicians to quickly identify and address potential problems in the network infrastructure.
