This is an important point: 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 to the failover port (to the port connected to your spare server or analog devices). While by itself that would be a pretty good design, there would be a vulnerability, because of course it's possible to have Asterisk crash while the server is still happily powered on. Therefore the Rhino failover device incorporates another design element: If you choose, you can enable its watchdog system. If asterisk stops responding to a periodic message, It knows that Asterisk is down, and fails over your services to the other server or analog devices EVEN IF the power is still on at the main server! -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
