We have a network of IBM PS/2 Model 70s and a Model 80 as a server running Novell software 286 V2.15 C. It is running on a token-ring at 4 Mbps. I'm a beginner at this Novell stuff but one of my tasks is to get it running at 16 Mbps. I tried using the Reference disks and setting all the machines to 16 Mbps but the software was flakey after that. There were noticeable delays after commands are issued. Sometimes, I'd get an network error: Error sending on network. Abort, Retry? Sometimes the retry works, sometimes it doesn't. I figured I must be doing something wrong so I reset everything back to 4 Mbps and decided to ask you all about it. What do I need to do to get this token-ring running at 16 Mbps with Novell? I've been looking through the manuals but I haven't found any mention of this. Suggestions?? This is probably an easy question but we've all got to start somewhere. Thanks much. Yan. -- )~ Yan K.

Thanks much. > Can't imagine why Novell would care about 4 or 16 mbit....there MIGHT be some timers (low level) which are being set wrong..but would expect these to be more trouble at 4 than 16. Any way you can beg, borrow, or steal a Lanalyzer....just as a wild guess, you might just be seeing a lot of MAC level errors on the medium as a result of the speed change. If you have a station on the ring set up as the Ring Error Monitor, look for an increase in Isolating and Non-Isolating errors when you increase the speed. Are you running UTP (Type 3 in Token Ring terms) or Type 1 or what? Any idea what your adjusted ring length is? How long are the lobe (drop) cables? And what type are they? How long are the trunk (Ring In/Ring Out) cables, (total length) and what type are they? > >Yan. >-- > )~ Yan K.

I should be Type 1 through out and atleast Type 6 for station patch cable. -- Jack Computer Support Corporation Dallas,Texas Hudler Internet: jack@cscdec.cs.com

First of all, you need 16mbs token ring network cards. ;-) -- __________________________________________________________ Ken Isacson Sysop - Board Of Trade BBS GT 016/001 kji@vpnet.chi.il.us (815) 753 - 0042 ----------------------------------------------------------

IBM has a demo where they do the reconfig on the fly. One minute your LAN is going 4Mbps and the next it is going 16Mbps! The IBMer giving the demo said that one of their techs reverse engineered the PS/2 setup disk and wrote code that does the reconfig dynamically. Only problem is all cards have to do it at once :)
