Server hardware not supported

[Dragomir]

I added in some b200 M4 blades into the UCs chassis and tried to reack the slot.

but got this error. I am running ucsm 2.1(3a)

any idea?

Hi Tony,

This message is expected as the B200M4 requires a minimum firmware of 2.2(3a) see below.  To resolve this issue you need to upgrade the UCS infrastructure firmware to at least version 2.2(3a)

Let me know if this helps
