Which hardware firewall platforms include both built-in front-to-back airflow and redundant power supplies?

Not all PA-5000 series models consistently include both front-to-back airflow and redundant power supplies across the entire series, making this option too broad.

Not all Palo Alto Networks hardware firewall platforms, especially entry-level or older models, come with both built-in front-to-back airflow and redundant power supplies.

The PA-3060 firewall platform, part of the Palo Alto Networks mid-range series, is engineered with redundant power supplies and front-to-back cooling, ensuring high availability and thermal efficiency critical for data center deployments. This design minimizes downtime risks associated with power failures and maintains optimal operating temperatures.

While PA-7000 series firewalls are high-end and include these features, the PA-3060 is a specific platform highlighted for consistently having both features in its class, and it is the chosen correct answer here.
