Red light on circuit board - Is it supposed to be on?

There is a green light which is on, on both of my boards but one board also has a red light on right beside the green.  

Is this supposed to be on? or is something wrong with the install?

 What kind of board is it I have 2 Konnected add-on boards and 1 Konnected Alarm Board, I don't have any of the interface boards.  None of my boards have a red light that I've noticed.  They have a blue light that would flash until I setup wifi and now that only flickers when a change is detected and info sent to my hub (which can supposedly be turned off from the hub side but I haven't tried that option).
