    Make sure that the last Ethernet interface (P12/ge12) is not used by any other configurations. For example, Policy Routes, NAT rules, VLAN interface base port, Zones, etc. This interface is used for Heartbeat port for keeping the devices linked together.

    You can select any device as the active device. 
    For example, device A is the active device and device B is the passive device. Remember to transfer all licenses from device B to device A before HA setup.
    On device A, follow the configuration guide on page 613 in the handbook to enter serial number of device A. 
    On device B, follow the configuration guide on page 614 in the handbook. 

    You can find detailed steps in the handbook.

    @ Zyxel_Emily thanks for the information. One more thing, when we connect the two USG FLEX 700 firewalls how they will make a selection for active and passive HA as there is no device role feature in the firewall.
