Desktop NGFW with PoE

The PA-455 is a desktop next-generation firewall that delivers 3.6 Gbps firewall throughput and 2.3 Gbps threat prevention throughput. It provides 4 PoE 1G RJ45 ports alongside combo and standard copper interfaces. Branch offices and retail sites needing integrated power for access points or cameras fit this platform.

Thermal and power profile

The unit draws up to 143.4 W when supplying 91 W of PoE output, operating from 100-240 VAC at 50-60 Hz. Maximum current consumption reaches 5 A at 12 VDC. A fan-cooled desktop chassis measuring 1.7" H x 9.4" D x 15.4" W and weighing 9.8 lbs manages heat in typical office environments.

Management and deployment extras

Two USB ports and both RJ45 and micro-USB console connections give local access options. An out-of-band management port separates admin traffic from production flows. Zero Touch Provisioning and Panorama central management simplify rollout across multiple sites, while active/active and active/passive high availability protect uptime.

Questions about this item

How do I install the PA-455 and what step is often missed?

Rack or shelf-mount the 1.7" H x 15.4" W x 9.4" D desktop chassis, connect 100-240 VAC power, then license and register the serial number before linking to Panorama or configuring local policies — skipping registration blocks all threat updates.

What maintenance or replacement will the PA-455 need later?

Replace the internal fan assembly when bearing noise appears, renew WildFire and Threat Prevention subscriptions annually to keep signatures current, and swap any PoE port module that exceeds the 91 W total budget after prolonged 45 °C operation.

Which limit appears first on the PA-455 under sustained heavy traffic?

The 143.4 W power ceiling with 91 W PoE load is reached before the 3.6 Gbps firewall or 2.3 Gbps threat-prevention throughput caps, forcing the unit to throttle interfaces or drop PoE devices.
