What problem is occurring when the LM5 Lite is flashing red?

Thank you for replying to me.

Really?

I have a test environment for LM at my workplace, so I have the opportunity to see it in an activated state on a daily basis, but I have never seen it.
As I mentioned the other day, the first and last time I saw the LED at the bottom flashing was when I was inspecting the equipment after the earthquake.
