Wall-plate AP light status when open the LED always-on

As we all know ceiling installed AP only has one LED light, so when we use the command of led-mode always-on , the result is obvious.

But when we use the wall-plate AP, what will happen when we use the command of led-mode always-on?

Only these two light will turn green, and other lights will keeps quiet.

Even when we plug the uplink port, the uplink light will not be turn green.

When we use the quiet mode, all the light will be turn off.
