The Emerson/Motorola CPX2408 is an 8-slot 6U CompactPCI chassis designed for industrial computing applications requiring flexible card configurations and field serviceability. This rack-mountable platform accommodates CPU modules up to 16HP wide and seven 4HP I/O slots, supporting both 33 MHz and 66 MHz operation with PICMG 2.16 or PICMG 2.0 R3.0 compliance. The chassis features five front-accessible 5.25-inch peripheral bays for drive integration, rear Transition Module support, and integrated cooling for sustained performance in demanding environments.
