I guess this is sort of on-topic, given I am talking about networking.

The Alpha 3000/800 I have contains a PMAF-FU card which is a DEC FDDIcontroller TURBOchannel card. It has a CAT 5 copper FDDI interface. I understand that it will support networking at 100MB.

I have no knowledge of FDDI. I believe that I would need a concentrator to make use of this connection, is there such a device which I could use to bridge the 3000/800 using FDDI to a standard ethernet network?


Yeah.   I had an ethernet switch that could take FDDI until a fan failed, the PSU got covered in weird goo, and it began arcing and tripping breakers.   The switch powered on fine a day or so later though...

As a second question, I have a number of DEC/Compaq/HP PCI FDDI cards which were given to me. They have optical connectors. If I were to make use of these would I need another concentrator, or is there a box which will support both media with plug in modules, for example.

If you get a modular concentrator I /think/ you can get optical, and copper modules in it at once.


Thanks for the help,

Mark.
