Initial High Availability Setup
Before you begin the configuration of HA on the Primary Dell
SonicWALL security appliance, perform the following setup:
• On the bottom panel of the secondary Dell SonicWALL
security appliance, locate the serial number and write the
number down. You need to enter this number in the High
Availability > Settings page.
• Verify that the primary and secondary Dell SonicWALL
security appliances are registered, running the same
SonicOS versions.
• Make sure the primary and secondary Dell SonicWALL
security appliances' LAN, WAN and other interfaces are
properly configured for failover.
• Connect the HA ports on the primary and secondary Dell
SonicWALL appliances with a CAT6-rated crossover cable
(red crossover cable). The primary and secondary Dell
SonicWALL security appliances must have a dedicated
connection using the HA interface. Dell SonicWALL
recommends cross-connecting the two together using a CAT
6 crossover Ethernet cable, but a connection using a
dedicated 100Mbps hub/switch is also valid.
