Determine PA-5450 Firewall Power Configuration Requirements

Learn about the minimum number of active power supplies required to provide sufficient power in different PA-5450 firewall configurations.
At least one active AC or DC power supply is required to operate a PA-5400 Series firewall. Factors that can change your power requirements are the number of Networking Cards (NCs) and Data Processor Cards (DPCs) used and your power redundancy requirement.
To determine the number of active power supplies required to operate the appliance, refer to PA-5400 Series Power Supply Chart and locate your model and power input type and then locate the column that coincides with the number of installed DPCs. Each power supply requirement in the table accounts for the installation of 1 or 2 NCs. To provide full redundancy, install double the minimum number of power supplies specified in the table. A fully redundant power configuration means that half of the installed power supplies can fail and the appliance and installed NCs and DPCs will still function.
