Anyone know what the error lights mean on a Cisco MCS78xx series server running call manager or unity? I cannot seem to find anything in Cisco's support and we have one with a red light. The symbol next to the light that is red looks like some sort of heart beat monitor wave with a box around it. The same symbol is right below that without the box and is green.

I am thinking it has something do with the health of the server but it does not indicate what the issue is or could be.
