Soekris Engineering net5501

This compact, low-power, low-cost, advanced communication computer is based on an up to 500 Mhz 586 class processor. It has four 10/100 Mbit ethernet ports, up to 1 Gbyte DDR-SDRAM main memory and uses a CompactFlash module for program and data storage. It can be expanded using a MiniPCI type III board, a hard drive and one or two low-power standard PCI boards. It has been optimized for use as a Firewall, VPN Router, Internet Gateway and VoIP PBX, but has the flexibility to take on a whole range of different functions as a communication appliance. The board is designed for long life and low power. It will be available in any volume in the standard version, and as board only or with a small metal box and various power supplies. The board can be customized according to requirements when ordering higher volume. net5501-60: 433 Mhz CPU, 256 Mbyte SDRAM, 4 Ethernet, 2 serial, USB connector, CF socket, IDE & SATA connector, 1 Mini-PCI socket, 3.3V PCI connector. net5501-70: 500 Mhz CPU, 512 Mbyte SDRAM, 4 Ethernet, 2 serial, USB connector, CF socket, IDE & SATA connector, 1 Mini-PCI socket, 3.3V PCI connector.
