Line 8: The shelf supports RTMs (Rear Transition Modules). RTMs plug into the back of the shelf in slot locations that match the front boards. The RTM and the front board are interconnected through a Zone-3 connector. The Zone-3 connector is not defined by the AdvancedTCA specification. Each shelf slot is 30.48 mm wide. This allows for 14-board chassis to be installed in a [[Rack_unit \| 19-inch rack-mountable system]] and 16 boards in an [[23-inch_rack \| ETSI]] rack-mountable system]]. A typical 14-slot system is 12U or 13U [[rack unit]]s high. The large AdvancedTCA shelves are targeted to the [[telecommunication]] market so the airflow goes in the front of the shelf, across the boards from bottom to top, and out the rear of the shelf. Smaller shelves that are used in enterprise applications typically have horizontal air flow. The small-medium AdvancedTCA shelves are targeted to the telecommunication market; for the lab research operation, some shelves have an open cover in order to make testing easier.
