Failover PIX

[samuel_M9]

Hi

I got PIX 525 with failover. Due to power issue one Unit was offline for a while. During this time couple of changes was done on the Firewall.

Which Unit becomes active when I plug the Firewall unit which was offline for a while now. Each Unit has 4 Ethernet Connection

E 0/0 - connects ISP Router

E 0/1 - connects to Lan switch

E 1/0 - connects to DMZ port

E 2/0 - connects to failover unit PIX

cheers

What is the problem Sam? Is it that you plug the offline unit and turn it on and it tries to become active?

I need to understand what to expect when I plug the 2nd box Online. If it takes as Active Role then I am in trouble if not then I guess should be ok. write standby command will help in replicating config.

Experts input your experience

You should be able to plug it without any issues. But I always recommend to do it on a maintenance window. A single communication issue on the failover link can cause a network outage.
