What color does the system LED display when the switch is powered and operational?

The system LED displays green when the switch is powered and operational. This green light signifies that the device is functioning correctly and is ready for use. In networking equipment, a green LED typically indicates that all systems are functioning normally without any errors or issues. It provides a visual confirmation to the user that the switch is in a healthy state and that traffic can flow through the device without any interruptions.

In contrast, other colors like red or amber often indicate different states such as errors, hardware failures, or other alerts that signify issues needing attention. Therefore, the green indication is a standard and reassuring signal that equipment is operating optimally.
