SCHROFF® FIRST TO MARKET WITH 12U 14-SLOT DEVELOPMENT SYSTEM DESIGNED FOR AdvancedTCAÔ

Warwick, RI, November 2002 - Schroff®, the global leader in electronic enclosure solutions, has released a new AdvancedTCAÔ 12U 14-slot development system. The enclosure is the first in a series of Schroff packaging solutions designed for the forthcoming PICMG 3.0 specification, called AdvancedTCA (ATCAÔ), being developed by the PCI Industrial Computers Manufacturers Group (PICMG®).

Schroffs new ATCA development system incorporates a full mesh 14-slot backplane installed in a 12U 84HP subrack; and is designed for heat dissipation of up to 120 W per board, with three cooling fans in an integral fan unit. The enclosure provides redundancy through dual IntelÒ ZT 7101 shelf management controllers and dual 48 V 60 A power input filters supplying 48 VDC power.

AdvancedTCA is PICMGs designation for the PICMG 3.x family of draft specifications. The open, multi-vendor ATCA architecture is designed to provide extremely high processor density and communications bandwidth, augmented with robust mechanical and electrical definitions. Although PICMG is developing ATCA specifically to address the need for central office grade equipment in the telecom sector, the architecture is also drawing heavy interest from the datacom and military equipment markets.

The new Schroff development system is available immediately. Other height and slot options are available upon request.
