Please look at the attached jpg. This is a simplified diagram of my client's network layout between 2 buildings, where there are Windows servers in one building, and PC's in the next building. Without going in to the gory details, they want to have a second "backup" Cat6 line, in case the current line dies.
Simply put, can there be two connections between the same network switches? In this case, these are "unmanaged" switches (or "dumb switches" as we call them).
I say "no", but I'm a programmer not a network guy ...
Will this cause some sort of problem? I think they can do this with a "managed" switch, but not an "unmanaged" switch.
