This is incorrect. According to Jim Rhodes at Rhino, there is no NEED for 'backup' power from another server via USB: As I described in the last post: "Not only does the loss of PC power NOT present a problem, is the main DESIGN element. If the PC/Server powers off, the relays naturally de-energize, which by design, PASSES the service [mechanically, as tne natural result of no power] to the failover port (to the port connected to your spare server or analog devices)" > "Christian Victor" <[EMAIL PROTECTED]> said: > > > Do you have an idea of its price ? > > Approx. US$ 700 > This is incorrect. Again, according to Jim Rhodes, the FULL nobody-ever-actually-pays-this-much LIST price is US $350. In my estimation, the street price will be between US $220 and $299 depending on your reseller's markup. I don't know if Rhino has M.A.P. rules.

I would have to ask the guys at Rhino for confirmation on this point but: My current understanding of the EXTERNAL usb connection is so that in the event that the secondary server NEEDS TO TAKE OVER the service for any reason, it can pre-empt the main server without the main server failing. Essentially the secondary server can 'ask' for it. -Karl _______________________________________________ -- Bandwidth and Colocation Provided by http://www.api-digital.com -- AstriCon 2008 - September 22 - 25 Phoenix, Arizona Register Now: http://www.astricon.net asterisk-users mailing list To UNSUBSCRIBE or update options visit: http://lists.digium.com/mailman/listinfo/asterisk-users
