Soekris Engineering

These two multiport ethernet adapters deliver excellent performance at competitive prices, and has been designed for long term availability for the embedded market.

The lan1621 is a short low profile PCI board with two independent ethernet controllers, perfect for space limited systems and 2U servers. The lan1641 is a short standard profile PCI board with four independent ethernet controllers, for systems where the highest number of ports are needed. Both boards can also be used for adding additional ethernet ports to the Soekris net4501, net4801, and net5501 communication computers.
