Perform the following steps:

Decide which interface to use for the additional connection between the appliances. The same 
interface must be selected on each appliance. For example, you could connect X4 on the 
Primary unit to X4 on the Backup, in which case X4 would be the HA Data Interface.

In the SonicOS Enhanced management interface, navigate to the Network > Interfaces page 
and ensure that the Zone is Unassigned for the intended HA Data Interface.

Using a standard Ethernet cable, connect the two interfaces directly to each other.

This section describes how to associate two SonicWALL appliances as a  High Availability Pair 
on mysonicwall.com, and shows an example high availability configuration on SonicOS 
Enhanced.

You can associate two SonicWALL security appliances as HA Primary and HA Secondary on 
MySonicWALL. Note that the Backup appliance of your High Availability Pair is referred to as 
the HA Secondary unit on MySonicWALL. After the appliances are associated as an HA Pair, 
they can share licenses.

You need only purchase a single set of licenses for the HA Primary appliance. The licenses are 
shared with the Backup unit. This includes the SonicOS Enhanced license, the Support 
subscription, and the security services licenses. The only licenses that are not shareable are 
for consulting services, such as the SonicWALL GMS Preventive Maintenance Service. 

It is not required that the Primary and Backup appliances have the same security services 
enabled. The security services settings will be automatically updated as part of the initial 
synchronization of settings. License synchronization is used so that the Backup appliance can 
maintain the same level of network protection provided before the failover.
