When does the STATUS LED indicate that the supervisor engine or module is online?

The STATUS LED indicates that the supervisor engine or module is online when it changes from orange to green. This signaling conveys that the device has completed its boot process and is fully operational. An orange light usually indicates an ongoing process or a failure, and transitioning to green signifies that the system has successfully passed its self-checks and is now functioning normally.

This kind of LED behavior is part of standard operational status indicators in Cisco devices, allowing users and technicians to quickly assess the health and readiness of the hardware at a glance. Other colors, such as red or continuous orange, typically signify errors or caution, denoting that the device is not fully operational or is still in a booting phase.
