Initial High Availability Setup
Before you begin the configuration of HA on the Primary
SonicWall security appliance, perform the following tasks:
• Determine which interfaces should be used as the HA
Control Link and the HA Data Link. Remember, they must
be the same ports on each appliance.
• Make a note of the serial number of the appliance that will
run as the Secondary device. You can find this on the
bottom of the appliance or in the System > Status page.
You need to enter this number in the High Availability >
Settings > HA Devices page.
• Verify that the Primary and Secondary appliances are
registered on MySonicWall and are running the same
SonicOS versions.
• Ensure that the Primary and Secondary security appliances'
LAN, WAN, and other interfaces are properly connected for
failover.
• Connect the HA Control and Data Links on the Primary and
Secondary appliances with appropriate cables.
• Turn on the Primary SonicWall security appliance first.
Then, turn on the Secondary SonicWall security appliance.
