Greetings, We have a client that wishes to install a 100Base-T network adapter (A3495-60001). After physically installing the card and connecting it via a CAT5 UTP fly-lead to a HP Switch800T/Advancestack Hub the link beat light never comes on. The 800T does not show the connection as being up either. I would have expected the network card to have indicated a successful connection to the switch with a link beat even though the network drivers have not yet started. I have tried to set the network card and the switch to autosense the connection. I have also tried to configure 10, 100 Mbit connections in both Simplex and Full duplex. Using NMMGR and on the 800T. Still no joy. Even after configuring the 100BaseT card in nmmgr, I am still not able to start networking and the link beat still does not come on. I consistently get the following error. <snip> INTERNAL ERROR; Device Open <snip> I have a 959 and a 968 both displaying the same behaviour. Both machines have been upgraded to PP4. All help greatly appreciated! Regards Jens von Bulow Neil Harvey & Associates
