I have a firewll PA-3050 version 5.0.11 and the High Availability cluster is configured Active / Passive mode. The interfaces to backup firewall are powered off and I tried switch the configuration in Active / Passive to auto instead shutdown, but the interfaces still powered off .
Can you help me ? How I can power on the interfaces in backup firewall ?

Is the firewall configured for Layer2 or Vwire? Review doc Passive Device Interfaces Down in Auto Passive Link State
When a cluster is Active/Passive the passive node interfaces do not pass any traffic. This is by design to prevent creating any layer 2 loops from any alternate paths created by having two devices serve the same traffic. Since the Active/Passive design is that only one firewall at a time is processing sessions, this generally does not create an issue.
If you network design requires that traffic pass on the inactive node, then you will need to implement an Active/Active cluster. This is the case if you need dynamic routing protocols to traverse the inactive device or if you have multiple network paths setup by design and want the cluster to handle asymmetrical routing.
It sounds like your network design method might require an Active/Active cluster deploy.
I am not sure if this is normal or not as all my clusters run Active/Active and I have not had time to lab up an active/passive one.
Can you test failover to see if it successfully shifts to the passive device?
Found the documentation for the link status in Active/Passive HA and this is a normal operation. The passive device interfaces can be link down when not in operation.
PA-850 firewalls when in Active/Passive with passive link state mode as "auto". All the interfaces on the passive device are down until a failover happens. During failover, passive takes over as active and all its interfaces are up and start forwarding traffic.
