MicroTCA.4 Chassis solves Power Redundancy Problem
VadaTech, Inc.now offers an 8U high chassis compliant with the MicroTCA.4 specification that offers N+1 redundant power to 4400W. MicroTCA.4 systems utilize double modules with an RTM connector for rear I/O. By adding RTM and higher power large modules, the overall power requirement in chassis are higher. Many High-Energy Physics and other applications require full power redundancy in the system. With specially designed power modules, the VT813 chassis from VadaTech has four 1100W power supplies in an N+1 redundant power configuration. By aligning the compact power supplies on the side of the card cage, the chassis can provide 12 double-module, mid-sized slots.
The backplane for the VT813 is 40GbE-ready, with a high dielectric material for clean signals. The chassis offers full redundancy, including dual fans trays in a push/pull configuration, dual MCH’s, and four power supplies. There are also dual FRU information devices and carrier locators, along with a JTAG Switch Module slot and a Telco Alarm built-in.
The VT813 is an 8U μTCA.4 chassis that provides 12 AMC mid-size double module slots that can accept any AMC.1, AMC.2, AMC.3 and/or AMC.4. It provides FCLKA, TCLKA, TCLKB, TCLKC and TCLKD to each slot. The VT813 has full redundancy. It’s capable of having redundant MCH, power modules, as well as redundant cooling units for high availability.
Ports 2-3, 12-15 and 17-20 are connected among the slots per the uTCA.4 recommendation. The VT813 has a Telco Alarm as well as redundant FRU information devices and carrier locators. The VT813 has a JSM slot which routes to each JTAG port of the AMC. The VT813 has provision to route cables from the front to back via channel below the card cage.
