[c-nsp] Failover questions (ASA)

Hello,

We;'re trying to setup a network with 2 Cisco ASA (5510) and 2 Cisco 
2950 switches. In event that any firewall kaputs, the other will take 
over (we havent decided on active/active or active/standby configuration 
yet). Also, all the servers on the internal network are performing 
"network teaming" , so even if one switch dies, traffic will pass 
through other traffic

FW1    --    SW1    --|
                    |            |  
FW2    --    SW2    --|

My question is, what if for some freak reason FW1 AND SW2 dies 
simultaneously. In this scenario, network is totally down unless we do 
some manual recabling. I understand that this might never ever happen, 
but i would like to see how i can plan for this, because this network is 
to be deployed in a remote location, where there might not be any IT 
people around to assist.

Appreciate any advise, or ideas on this. Thanks!
