Hi, 
 Thank you for reaching out to Sophos Community. 
 You must put the license on your primary device/firewall. 
 Suppose I understand correctly, for Central. This will automatically switch to HA mode even if you register them separately. 
 You may access the Auxillary device via Peer Administration IP. 
 For example. I've registered both my Firewalls in Central separately. However, when I turned on HA, it switched to the following.

Aso, I'll be moving the post to Firewall Forum.
