Current Unleashed code allows you to define a management IP address for all APs (1 - 25) that will always be your browser target address to reach.
It then doesn't matter which AP is acting in any role (unless you setup gateway mode), but you have failover capability, mesh if needed, etc, versus
running both APs in Solo/Standalone mode (which is what I thought you were asking for originally and would be necessary to load different firmware

As mentioned above, from the one Unleashed management GUI, all Networks (WLAN/SSIDs) created are advertised by all Unleashed APs.
