Build a cleaner firewall rack with a tray designed for the PA-400 series. The PAN-PA-400-RACKTRAY supports one or two PA-440, PA-450, or PA-460 firewalls in a four-post 19-inch equipment rack, giving infrastructure teams a more orderly way to mount and service appliances in space-constrained environments. The tray’s metal construction and rail-based design help keep the installation structured, while the ability to accommodate up to two firewalls and 4 power adapters supports denser deployments without resorting to improvised mounting methods. That matters when you are standardizing branch security stacks, consolidating equipment in network closets, or building repeatable rack layouts across multiple sites. This is the kind of accessory that earns its place in a premium deployment: it reduces physical clutter, supports consistent placement, and aligns with the operational discipline expected in enterprise firewall environments. It is specifically intended for PA-440, PA-450, and PA-460 models, and should not be used with PA-410.
