2197.0. "DETMIs to create different LANs in a DEChub90" by DRAC::63795::LLUIS () Tue Apr 18 1995 13:01

Hi everybody,

can I use a DEChub90 and 3 DETMI's to create a three ethernet backplane
without any connections between each other?.

Somewhere I read that HubWatch allows to disconnect DETMI's from the
thinwire segment, is it true?.

Thanks in advance,

Llu�s

Hi,

it will not work because you cannot have anything other than one "ThinWire" 
segment in DEChub 90.

    It is true that, via hubwatch, the DETMIs can be disconnected from the
    thinwire segment.
    
    You can put three DETMIs in a HUB90 and disconnenct each from the
    backplane thinwire segment.  This would give you three independent
    network segments with eight TP ports on each.  But you might have
    trouble when it came time to attach those segments into the rest of 
    the network, if that is your intention.  If you used the thinwire, 
    the three DETMIs would no longer represent independent network 
    segments because of the thinwire connection.  A front-panel TP port on
    each DETMI could possibly be used for such a connection, but this would
    steal one of the user ports from each segment.
    
    If the three DETMIs were standalone, you'd have more options because
    the thinwire ports wouldn't be permanently attached to the same
    physical segment, and also because of the availability of the
    rear-cover AUI port.
    
    If you provide more detail on what you're trying to accomplish, maybe
    we can make some concrete suggestions.
