- Disable T1/E1 interface
- Disable switch controller. Type following command in console:
config system global
set switch-controller disable
end - Make sure WAN interface is using STATIC IP not DHCP or PPPOE. (In Ver.5.2.14, It can not change to PPPOE even after HA setup done)
- It need least 2 heartbeat lines. Use HA port and the other ports.
