Correct procedure to replace failed secondary ASA unit

endpoint
Beginner
Beginner

Hello

i just received a RMA for failed ASA 5520 that was acting as secondary unit in multicontext configuration. What would be correct procedure to install it back in production? Do i need to restore backed up config of the fallen unit or is it just enough to enable multimode and connect to existing (primary) unit? Any good link for documentation that deal with this issues would be also appreciated.

Thanks in advance

Configure the ASA for failover communication and as a secondary unit. This is done from the system context so yes you need to switch it into the multiple context routed mode. Power the asa on and connect only the failover communication interface. This will make sure that it is seen by the primary as failed. Once the failover communication is up, and the configutation synchronisation and connection replicatiin are over, connect the traffic interfaces.

This is pretty much it. Hope it helps.
