[comp.misc] Problems with Synoptics 2530?? Help and request for info.

dryfoos@duke.cs.duke.edu (James D. Dryfoos) (05/17/91)

Has anyone had the following (or any other) problem using 
a Synoptics 2530 concentrator (lattice net)?

The network config is:

Novell network  ---> Novell server w/internal bridge 
                        |
                        |
                        --> 2530  --> bridge --> backbone
                                                   |
                                                Novel Server

Work stations on the Novell network can connect
to the Novell server with no problem.  However, when
going thorugh the internal bridge and trying to connect to
a server on the backbone, the responce is so slow (packets get through)
that it usually times out.  If we replace the 2530 with another
product everything works fine.  Synoptics says the 2530 is good and
that the problem is with our net.  We have had other problems with
2530's and no problems with any other vendors equipment.

Has anyone else had 2530 problems?  We once had a bad batch from the
factory, and were first told the problem was with another company's
product that we were using (this of course was wrong).

Synoptics claims there is a propogation delay problem.  Doesn't
the bridge avoid that?  There certainly is no problem
on the 2530 side of the bridge as the side is small in comparison --
and after all, other vendors equipment works.

Appreciate any feedback on this -- even info on propogation delay and
bridges.  Also if there is a better place to post this I would
appreciate that.

Thanks in advance.  Jim Dryfoos
