Ex2 Ultra 2nd bay is red Solid

I have in my ex2 ultra 2 wd red 3tb both are fine and full function on the 1 bay but when I put a disc in the 2 bay it shows a red solid color, I repeat is not the disk I try changin it but nothing happends, in the control panel it shows degraded but it is not what can I do?

You may want to post your question/issue to the dedicated EX2 subforum where people more knowledgeable with the EX2 may be able to assist. This subforum (My Cloud) generally deals with the single bay My Cloud units.
