We have exactly the same problem when connecting this switch to a FitPC3 http://www.fit-pc.com/web/products/fit-pc3/ We have tested it with different switches of that type, with different cables and with different FitPCs. No SF100D-05 works with any FitPC3. The Switch works fine with other computers and the FitPS works fine with other switches but the SF100D-05 does not work with the FitPC3. So eather the FitPC or the Switch has a problem. So we shipped 8 of this Switches the long way to Nepal and they are useless now. So any solution would be very apprechiated.
