The G650 is a port network cabinet that contains "TN" form factor circut packs. The TN circut packs that have downloadable firmware, and are upgradeable are covered in the compaibility matrix. There are two versions of the compatibility matrix; a document version and the compatibility matrix tool. The document version is linked to the CM download page where you can also obtain the TN FW downloads:
The tool version of the compatibility matrix includes the same information as the document (Primary Components) in addition to Compatible Avaya Products. The tool is updated after the document is updated.
