IntroductionThe SCB-7903 is a 1U Rack-mount hardware platform designed for network service applications. Built with Intel® EmbeddedIA components with warranty of longevity, the SCB-7903 supports Intel® Celeron® Bay Trail-D and Bay Trail-M low-voltage processor.

The platform supports high bandwidth DDR3L SODIMM slot with memory up to 8GB. In order to provide the best network performance and best utilization, the powerful storage interfaces include two 2.5” or one 3.5” SATA HDD and CompactFlash™.SCB-7903 affords six GbE Copper with Two pairs bypass function on front-panel. The front panel also has two USB 2.0 port,one RJ-45 console port and LED indicators that monitor power and storage device activities for local system management, maintenance and diagnostics. In addition, the SCB-7903 supports one PCI-E connector and is RoHS, FCC and CE compliant.
