The PA-5400 Series firewalls (PA-5410, PA-5420, PA-5430, PA-5440, PA-5445, and PA-5450) are high performance appliances designed for large enterprise environments, data centers, and internet gateway deployments.

The PA-5410, PA-5420, PA-5430, PA-5440, and PA-5445 firewalls provide flexibility in performance and redundancy to adapt to your deployment requirements. These models can use either AC or DC power. Dedicated computing and hardware resources ensure predictable performance in networking, security, signature matching, and management functions.

The PA-5450 is a modular appliance that utilizes Networking Cards (NCs) and Data Processor Cards (DPCs) to scale network interfaces and data processing power as needed. In the PA-5450, you can install up to two NCs and four to five DPCs depending on your front slot configuration. These firewalls also feature a replaceable Base Card (BC) that interfaces with the signal connectors of the seven front slots, power supplies, and fan connections. Integrated with the BC is the Management Processor Card (MPC) that provides two logging ports, two management ports, and two HA1 ports for high availability deployments. The PA-5450 can leverage either AC or DC power.
