Caution –
The systems ship from the factory with all boards assigned to
domain A.
You can do some very screwy things with segments & domains.
We have seen dual segment 6800s with one domain, which means you are
driving the domain from two repeaters not four.
We have seen domain A on a 6800 with odd numbered sb/ib’s and
domain C with even numbered sb/ib’s.
Make sure you understand the issues when setting up segments &
domains.
