Seems like you are not running 2.2.3a (or later) for UCSM  The release notes:  http://www.cisco.com/c/en/us/td/docs/unified_computing/ucs/release/notes/ucs_2_2_rn.html#pgfId-238846 ; under  "New Hardware Features in Release 2.2" shows that is the version that will make UCSM recognize the new M4 servers.

If this is the answer to your issue, please mark it as such for future users to find their answer as well.
