Elma Electronic Inc. offers an improved version of its 5U AdvancedTCA (ATCA) chassis with full redundancy, giving the unit high availability features in a compact horizontal format. The system platform offers dual redundant fan trays, shelf managers and A/C power supply options.

The 2nd Gen 5U AdvancedTCA chassis features side-to-side cooling via plug-in fan trays with dual 170-CFM fans with pulse width modulation control. The redundant push/pull configurations of the fans offer higher levels of reliability and reach the back of the chassis for cooling the rear I/O slots. The chassis offers dual 1,200W AC power supplies and dual shelf managers, which are all front-pluggable above the card cage. DC power versions are also available.

The 5U ATCA chassis is a 19-inch rackmount unit with rugged steel construction. The system platform features a second generation shelf manager with bussed or quasi-radial Intelligent Platform Management Bus routing. A unique 5-slot ATCA backplane provides specially placed connectors for pluggability. Full mesh, replicated mesh and Dual Star topologies can be implemented on the same backplane. The backplane uses a standard AMC connector for plugging to Elma's 2nd Gen shelf manager. A 6-slot backplane is also optional in certain configurations.

In addition, Elma's board mating receptacle on the card guides provides secure grounding, accurate alignment and accepts wide tolerances of the alignment pin spacing. Other chassis features include dual on/off switches on each side of the rear of the enclosure and NEBS-grade washable air filters, which are attached via Velcro to the filter trays. For serviceability, the filter tray and fan tray are removable.

The 2nd Gen 5U AdvancedTCA chassis is available for less than $2,500 depending on volume and options. Delivery is four to six weeks.
