Replacing a SonicWALL Security Appliance
If your SonicWALL security appliance has a hardware failure while still under warranty,
SonicWALL will replace it. In this case, you need to remove the HA association containing the
failed appliance in MySonicWALL, and add a new HA association that includes the
replacement. If you contact SonicWALL Technical Support to arrange the replacement (known
as an RMA), Support will often take care of this for you.
