[admin_2]

We want to choose two pix535.They work in failover mode.Pix535 has three type:

PIX-535-R-BUN, PIX-535-UR-BUN, PIX-535-FO-BUN.What is the difference between them? Which mode should I choose?

PIX-535-FO-BUN is used for failover scheme. PIX-535-R-BUN refers to a restricted software number of licensed and PIX-535-UR-BUN includes an unrestricted software license.

I believe that you require a PIX-535-UR-BUN and a PIX-535-FO-BUN to do the failover. One is in standby while the other carries data. They have to be connected by a special cable and a 10baseT connecion. You should verify this information with Cisco TAC before you order.
