I have some more question about HW and PIX failover.
What happens when I connect two PIXs..
one UR license and one FO license and my
FO PIX takes activity over and my PIX with UR license will be corrupted so that I will need to disconnect it completely to repair it? I know that when someone wants to use FO PIX standalone than PIX reboots per 24 hours cycle. How PIX determines that it is not used standalone? I think that when I switch off first PIX in pair so second PIX in pair with FO license will function standalone.
So, when the PIX pair powers up, both units detect each other. If you then later remove the UR PIX from the mix, the FO will remain up and actively passing traffic indefinately. (Or almost so. At least until the next power outage). The licensing restriction only kicks in if the FO unit does not detect a UR unit at boot.
If this answers your question (I believe it does) please check the box so we can see one of those nice red checks :-)
