How to add a FleXi module to an existing HA pair

To add a FleXi port module to an existing HA pair, do as follows:

  1. Turn off both firewalls.
  2. Install the FleXi port modules in both firewalls. You must use the same model of FleXi port module in both firewalls.
  3. Turn on both firewalls.
  4. Go to Network > Interfaces and assign an IP address to the FleXi port. Synchronization takes place, and the FleXi port of the auxiliary firewall is assigned the same IP address.
  5. Click Save to allow traffic flow.
