Question
HP UID Light
I have an HP ProLiant DL380 G5 Server. On the front of the server there is a button labeled UID. Through HP's System Management Homepage I am able to turn the light on or off. When it is on the light is blue. What is the point of this button/light? What happens if I push the button?
