Abstract
With this disclosure, we can activate debug LEDs manually when we need them, especially for the service
team. Service usually requires debug LEDs on the boards to easily determine whether the board power is
normal or not. But with more LEDs, comes more power consumption, and more chances to have light
leakage. When a system is power consumption sensitive, or has lots of opening on its chassis, this design
can solve the low power and special chassis problems.
