8/12/2004 - Elma Electronic Inc., a global manufacturer of electronic packaging products and rotary components, has announced that it has upgraded its 12U ATCA chassis line with several advanced and unique features.
The new 12U ATCA is fully redundant from top to bottom. Three plug removable fan trays offer a total of six high volumetric 130CFM fans, three in the top/rear and three below the card cage. This includes coverage of the rear I/O card cage and the top fans are angled slightly to direct exhaust out. The reap top of the chassis is also angled, allowing more airflow exhaust to escape when multiple chassis are stacked on top of each other in a rack.
With Elma's thermal simulation engineering, the chassis has been optimized for maximized cooling capability. The simulation allowed the company to perfect the ideal intake and exhaust areas, determine the best fans and fan configuration, and optimize the air baffles to redirect airflow. Moreover, the company can make further adjustments after simulating the chassis along with a customer's boards to maximize the actual system cooling for that specific application. Testing performed on the Elma 12U chassis verifies the chassis meets the 200 W/slot cooling required for ATCA.
With "pluggability and redundancy everywhere", the 12U ATCA offers dual Power Entry Modules (PEMs), dual shelf management modules, dual fabric slots, etc. The PEMs allows pluggable 48 DC feeds with I2C shelf manager interface. They can handle 100A per module. The optional IPM Sentry shelf managers come in dual redundant pluggable units, which are located below the bottom fan tray and are recessed.
The chassis features a special 7U ATCA backplane inside with a 14-slot Dual Star topology. It has headers below the card cage area for pluggable fan trays, shelf managers, power entry modules, etc. Compliant to the PICMG 3.0 specifications, the 12U ATCA chassis also has rear I/O options.
