Replacing an SNS firewall through an RMA
If you need to replace a firewall that the SMC server manages, follow the usual procedure for replacing an appliance through an RMA (Return Material Authorization).
After you have restored the firewall’s configuration on the new appliance using the .na backup file, the firewall will automatically log back on to the SMC server. There is nothing additional that you need to do; there is no need to generate a new connecting package.
