<div>I was believing that these 3 physical LEDs(Identify, Fault, Power) will be lit on/off based on group LED asserted state. Example: Physical's fault LED will be lit ON when any fault LED(e.g. cpu0fault) in group is asserted.</div>
<div>If that is not the case and we need to rely on below LED groups to get full system status then - how are we going to display state like blink in future using these group LED?</div>

What are you trying to use the physical<br>LED for that you would like some kind of consistent naming and are you<br>sure the group would not be more appropriate for your purpose?<br><br>--<br>Patrick Williams</font></div>
