# ac922interposer
The purpose of this design is to enable the AC922 to accept a DC-SCM v1.0 hardware management module. This enables a developement
platform for software development.
For connection with a DC-SCM, the DC-SCM v1.0 release design specifies the connector as an SFF-TA-1002 compliant 4C+ connector. The 4C+ connector is a 4C compliant connector with an additional 28-pin “OCP bay” defined in the OCP NIC 3.0 specification. The right-angled variety allows for the DC-SCM to lay within the BMC cage assembly. This can be implemented with TE 2336568-1.
