System Chassis Features

The system chassis is an easy-to-expand, fabricated metal structure housing the power supplies, fans, expansion bays, system board, and supporting components. A key feature of the chassis is the “swing-out” electronics bay and subchassis modules, allowing easy access to the interior of the system.
