Soekris Engineering, Inc.'s lan1841

The US-manufactured lan1841 from Soekris Engineering, Inc., is a short standard-profile PCI Express board featuring four independent Intel 82574L Gigabit Ethernet controllers for systems where the highest number of ports is required. The lan1841 is designed to work either with the Soekris net6501 for communications applications or as a standalone PCI Express LAN card. Together with the Soekris' net6501 series featuring a 1U 19" rackmount case, the net6501 PCI-Express riser and two lan1841s, users can configure a reliable, low-power rackmount unit with 12 ports. Alternatively, those looking for a four-port PCI Express Gigabit LAN card at a reasonable price for use with other hardware will find their needs met as well. The lan1841 features a three-year warranty.
