Initial High Availability Setup
Before you begin the configuration of HA on the Primary
SonicWALL security appliance, perform the following setup:
1. On the bottom panel of the Backup SonicWALL security
appliance, locate the serial number and write the number
down. You need to enter this number in the High
Availability > Settings page.
2. Verify that the Primary SonicWALL and Backup
SonicWALL security appliances are registered, running the
same SonicOS Enhanced versions, and running the same
SonicWALL Security services.
3. Make sure the Primary SonicWALL and Backup
SonicWALL security appliances’ LAN, WAN and other
interfaces are properly configured for failover.
4. Connect the X5 ports on the Primary SonicWALL and
Backup SonicWALL appliances with a CAT6-rated
crossover cable (red crossover cable). The Primary and
Backup SonicWALL security appliances must have a
dedicated connection. SonicWALL recommends cross-
connecting the two together using a CAT6 crossover
Ethernet cable, but a connection using a dedicated hub/
switch is also valid.
5. Power up the Primary SonicWALL security appliance, and
then power up the Backup SonicWALL security appliance.
6. Do not make any configuration changes to the Primary’s
HA interface; the High Availability configuration in an
upcoming step takes care of this issue. When done,
disconnect the workstation.
