The choice is really big, Google gives many vendors and a wide range of models of Ethernet protectors. > - and define your 'galvanic isolation' ;-) Well, er, http://en.wikipedia.org/wiki/Galvanic_isolation ;-) There are many methods, optical is one of them. What kind of optical isolation devices do you use? When I worked as a sound operator many years ago we used the transformer method a lot. In fact, our mixing consoles had symmetric transformer inputs. But I digress. > > > You are not advising them from your own experience, are you? > > nope.

I will report later which model is that. The location where the last switch died is remote and normally unmanned. -- Victor Sudakov, VAS4-RIPE, VAS47-RIPN sip:[email protected] _______________________________________________ cisco-nsp mailing list [email protected] https://puck.nether.net/mailman/listinfo/cisco-nsp archive at http://puck.nether.net/pipermail/cisco-nsp/
