NO, the failover cable is what makes failover possible. The cable is configured so that one end connects specifically to the failover PIX and one end connects to the Master PIX. When you plug in the secondary PIX it automatically downloads a copy of the config. You can add an aditional cable called a "stateful" failover cable. This allows failover without dropping connections. I once dialed up to an external ISP, made a VPN connection to our PIX, walked back to the wiring room and pulled the plug on the main PIX firewall. The VPN connection stayed up... didn't miss a beat. Now that is a nice feature!
