Hi, you can try looking into "switch fault tolerance" teaming mode, this mode will trigger if the primary switch went down, need to enable STP on the 2 switch.
more details on teaming can be found in this link - http://www.intel.com/support/network/sb/cs-009747.htm?wapkw=%28CS-009747%29
hope this help.
I see, but you said that ; when the switch went down...i was wondering when the switch uplink is down, so switch is up but uplink port which is connected to backbone or firewall etc. is down.
