The Aitech E117 is a cold plate cooled 11-slot VME64 compliant rugged computer enclosure, specially designed for space applications. Up to two drop-in power supplies can be installed to provide redundancy in highly critical operations. The power supplies operate in a load-sharing configuration to minimize stress and increase longevity. In case of power supply failure, the remaining power supply takes up the loadensuring uninterrupted operation.
The E117 features an extended height toaccommodate fiber optic cables.
Sturdy Mechanical Design
The design of the E117 has been optimized to provide maximum strength with minimum weight. Constructed of durable CNC-machined 6061-T6 aluminum, the chassis is assembled using stainless steel fasteners to prevent corrosion. Often-used threads have self-locking stainless steel helicoils to withstand severe vibration and shock. All connectors are located on the front panel of the enclosure for easy access. All external surfaces, with the exception of the cold plate interface, are hard anodized coated for excellent corrosion resistance. The cold platemating surface is precision machined to ensure
excellent heat transfer to the cold plate, and it is configurable to meet any customer-mounting requirements.
The E117 accommodates 11 standard VME/VME64 boards with 0.8 inch pitch, including:
- IEEE 1101.2 conduction-cooled VME cards
- Commercial VME boards without front panels
The backplane is VME64 compliant with an 1-row J1 and J2 connectors in all slots. VME64x compliance with P0 connectors in some or all slots is optionally available. For ease and flexibility of harnessing, up to 640 I/O signals are routed from the VME J2 connectors to four 160-pin staging area.
