NetCom D90

The NetCom D90 is a great compact network appliance powered by a Via C7 processor, with ethernet options from one 10/100Mpbs port to one 10/100Mpbs port + three 10/100/1000 ports

The fanless aluminum and steel case provides protection in environments where dust and dirt predominate and are ideal for locations requiring silent operation. Heat generated by the system is dissipated by the dual purpose aluminum case, that is designed with fins, similar to a heatsink, and heatpipes that draw heat away from the processor. The fanless design improves system reliabiltiy by preventing potential mechanical failures.

For mission critical network applications the hard disk drive can be replaced with a solid state drive to become a shock proof and noise free reliable system with no moving parts that could potentially fail.

VIA C7 Processor with 21 mm NanoBGA2 Technology

The new VIA C7® processor is the smallest, lowest power, most efficient and most secure native x86 processor in the world. Built on the advanced VIA CoolStream architecture, the 'Esther' core of the VIA C7 processor is designed to provide robust performance of up to 2.0GHz with ultra low power consumption and highly efficient heat dissipation.

Low Power by Design
Developed from the ground up for low power operation, the VIA C7 processor is based on the advanced VIA CoolStream™ Architecture and manufactured using state-of-the-art 90nm Silicon-on-Insulator (SOI) process, and delivers the greatest performance per watt in the business.

The onboard 1.5GHz processor has an ultra low power consumption of around 12 watts peak power and operating at an average power of less than 1 watt.

Fanless System, for ultimate reliability

Fanless Systems are great for environments where dust and dirt predominate and are ideal for locations requiring silent operation. Our systems utilize heat pipe technology and aluminum fins for passive cooling. The absence of moving fans reduces the failure rate of systems in harsh environments.

In addition to being fanless this system offers a sealed enclosure from the elements. Even in the most clean and climate-controlled environments, dust and potentially conductive debris will be infused into the unit over time. The picture to the left shows a unit that was returned for service after approximately two years of operation in a computer room environment (not generally considered to be a harsh environment). Infused debris can cause bridging of circuits due to conductive material coming to rest across insulating barriers. Alternately, dust build up acts as a reservoir for ionic contaminates and moisture entrapment from humidity. Over time, these can enable the growth of conductive dendrites that may ultimately bridge insulating barriers
