We are adding a second PIX 515 with a FO license as a failover device.
I am concerned about what will happen in the event of a failover. Specifically, the documentation says to not use a FO device as a standalone because it will automatically reboot once every 24 hours. What will happen if I am out of town for 1 week, and the power supply of the primary device dies. Will the secondary device be rebooting every 24 hours because it thinks it is now being used as a stand-alone device? The primary device is "gone" now, after all. Or, will the FO device run for an indefinite period of time without rebooting?
