Re: Twinax probs

[Pat Barber <mboceanside@xxxxxxxxxxxxxxxx>]

I think you are "mixing" wiring methods...

Twinax doesn't generally use muxs, are you sure about this being 
twinax ??? What is the purpose of the mux ??

You refer to "controllers" several times, "which" controllers
are you working with and what are using to check them with ??

One device on a twinax line would not normally "drag down" all the
other devices "unless" it was the first device on the line and it
failed quite badly, it "might" bring down other devices by not
allowing communications. The device status on any line can be
checked with wrkcfgsts *dev and making note if a printer has a 
associated writer started. You can also determine if displays are 
working this way.
