How to make UCS blade server led health state abnormal

[liyujoy]

In general, UCS blade server health led state is normal. I am testing the UCS blade server with all possible health led states. But I can't reproduce abnormal health led state. So in which circumstance, the UCS blade server health led status can be abnormal. e.g. minor, critical?

The severity of the alarm. This can be one of the following:-

Critical—The blade health LED is blinking amber

Minor—The blade health LED is amber

If you intentionally want to fail some component, i can only think of removing the one HDD which is already in RAID. Blades changes LED color for so may reasons - dimm failure, hdd failure, cmos battery failure etc... few of them in above examples are controller & mezz card fault.
