I installed ASA5520 pair in transparent mode for the server farm in one of my customer data center. The server farm switches are 3750 with stacked using the stacking cable.
When i found the primary firewall in standby i used in console "failover active" to bring it to the active state.
As soon as this FW comes active all the server farms switch ports LEDs are blinking fast and some of the server seems reseted. The whole network down untill again we brought back the standby secondary firewall to the active by no failover active in primary FW.
What went wrong during the FW switchover to the active state.
Also how can we access the ASDM using the management 0/0 interface.
I need to have the sample config.
