[HECnet] FDDI advice

If you mean a RU, Rack Unit...that's 1.75". -Dave On 10/10/2013 01:08 PM, Hans Vlems wrote: A hu is two inches, right? *Van: *Brian Hechinger *Verzonden: *donderdag 10 oktober 2013 16:35 *Aan: *hecnet at Update.UU.SE *Beantwoorden: *hecnet at Update.UU.SE *Onderwerp: *Re: [HECnet] FDDI advice On Thu, Oct 10, 2013 at 02:32:26PM +0000, Paul_Koning at Dell.com wrote: On Oct 10, 2013, at 8:44 AM, Brian Hechinger <wonko at 4amlunch.net> wrote: On Thu, Oct 10, 2013 at 02:36:04PM +0200, Peter Lothberg wrote: ... For example cisco/cabletron/crecendo had ethnernet switches with a FDDI uplink, that you could use. DEC made one as well, it was that large modular thingie. I used to have one. Never got it powered on as it was enormous. The original one is the DECbridge 500, a 3U rack mounted device, 3 or 4 cards, 3 Ethernets (10 Mb/s) to FDDI. See the DTJ issue I mentioned in my previous note. The other two: the DECbridge 900, which plugged into the 900 series modular enclosure. It's about the side of a 400 page hardcover book, FDDI to 6 Ethernet ports, 60,000 packets per second using a MC68040 at 25 MHz. I'm still proud of that. (I wrote the "fast path" packet forwarding firmware.) Neat! Then there is the Gigaswitch, a large modular chassis with lots of line cards, some FDDI, some Ethernet, possibly some with other stuff I don't remember. I think this is the one I had. Big modular thing. Maybe (and going by really fuzzy memory here) 8U high? -brian -- Dave McGuire, AK4HZ New Kensington, PA
