This compact, low-power, low-cost, advanced communication computer is based on an up to 266 Mhz 586 class processor. It has three 10/100 Mbit ethernet ports, up to 256 Mbyte SDRAM main memory and uses a CompactFlash module for program and data storage. It can be expanded using a MiniPCI type III board and a low-power standard PCI board.

It has been optimized for use as a Firewall, VPN Router and Internet Gateway, 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.

Please note that this product has reached end of life status.

The net4801-48 are still available in small/medium volume, as board only or with a small metal box and various power supplies.

With an HDD mounting kit you can install a 2.5" HDD on top of the board.

Cases are available for inserting lan1621, lan1641 and Sangoma boards.
