Description of LED HMI functionality
On the top-plate of each SAM600 module, there are three status LEDs which have
a fixed function and cannot be configured.
The function of each LED is as follows:
The green LED (READY) indicates the health status of a SAM600 module.
The yellow LED (WARNING) indicates any warning caused by an issue
related to a SAM600 module.
The red LED (ALARM) indicates severe hardware failure or software
malfunction of the SAM600 module.
