VadaTech VT931: 4U Rugged MTCA.1 Chassis with 12 AMC Slots and Advanced Cooling

VadaTech, a leader in rugged networking hardware, introduces the VT931, a 4U MicroTCA.1 chassis engineered for mission‑critical deployments. The enclosure delivers 12 AMC slots that support AMC.1 through AMC.4 modules, giving system integrators unparalleled flexibility.

Robust Design for Harsh Environments

The VT931 is built to MTCA.1 specifications with perforated top and bottom panels that channel airflow directly to the upper fan tray. The chassis inherits the proven 4U form factor of the VT930, enhanced by an integrated, removable cooling unit that keeps power consumption and thermal load low.

Dual‑Star Backplane & High‑Speed Connectivity

Featuring a Dual‑Star backplane, the VT931 offers either 40 GbE or PCIe Gen3 throughput, ensuring low‑latency data paths for demanding applications. VadaTech’s signal‑integrity optimizations reduce cross‑talk and maintain clean links across the board.

Redundant Identification & Easy Maintenance

Dual redundant FRU information and carrier locators are configured via accessible mechanical dip switches. Because the switches are removable, the backplane remains passive when not in use. The MCH reads the locator through a dedicated I²C bus.

Smart Cooling & Remote Monitoring

Cooling airflow travels from bottom to top, controlled by a single intelligent unit mounted on the upper AMC rail in a pull configuration. Multiple temperature sensors monitor intake and exhaust temperatures throughout the chassis. A management controller accesses these readings over a redundant IPMI bus, enabling proactive thermal management.

The fan tray is removable, simplifying routine maintenance without compromising structural integrity.
