Custom 19” Fan Tray

Verotec (Derry, NH) recently custom designed intelligent fan trays for a major defence project. The 19-inch rackmounted 1U trays have six fans, strategically located within the tray to maximise the cooling of critical elements of the electronic system located above the fan tray. Key issues for the fan tray design were noise levels, current consumption and reliability. A custom control board sequentially powers up each of the fans in order of importance to minimise initial inrush current. An embedded microprocessor controls fan speed using PWM technology.

Reliability is critical, so three separate events will trigger a warning signal: if power is lost to the fan tray, if the controller board itself develops a fault or if the speed of any fan falls below 20% of maximum. The fan cooling the main processor board is deemed to be a critical component, so if its speed falls below 20% the relay latches into the alarm position. If triggered by any of the other five fans, the alarm relay will re-energise when the speed increases above the 20% threshold.

Rugged 1U MicroTCA Chassis Platform

VadaTech (Henderson, NV) now offers a rugged 6-slot MicroTCA chassis in a 1U height designed to meet MIL-STD- 901D and 810G for shock and vibration and MIL-STD-461F for EMI. The VT950 holds up to 6 Advanced Mezzanine Cards (AMCs) and has an integrated MCH with IEEE1588/SyncE/GPS capabilities. This includes clock disciplining with arbitrary clock frequency output and holdover (Stratum-3 option) including 1 pulse per second (PPS) regeneration and holdover. The MCH can use various fabrics such as 40GbE/10GbE, PCIe Gen 3, or Serial RapidIO.

The rugged 1U chassis offers front-to-rear cooling with a 500W universal AC or 400W DC power supply. Another feature of the VT950 is an optional JTAG Switch Module, including a Virtual JTAG probe. MicroTCA.1 modules with front panel retention screws can be plugged into the chassis. VadaTech offers special retention clips so that standard MicroTCA. 0 AMCs can be securely held into the chassis during shock and vibration.

Embedded Switch Fabrics

Mercury Systems, Inc. (Chelmsford, MA) has announced its Micro Via Radial Interconnect (MVRI) technology. MVRI improves OpenVPX™ switch fabric interconnect data rates by increasing the signal integrity margin approximately three-fold, enabling switch fabrics and point-to-point connections to run faster and more reliably. MVRI technology is scalable, enabling it to support signaling rates greater than 14 wGbaud per channel. Planned future fabric implementations, using InfiniBand enhanced data rate (EDR) or 100Gb Ethernet, especially benefit from the performance boost MVRI technology delivers. Intel® Xeon® server-class OpenVPX ecosystems in combination with the latest InfiniBand and Ethernet switch fabrics provide the embedded processing capability needed for challenging electronic warfare (EW) and C4ISR processing applications.
