Determine PA-5400 Series Firewall Power Configuration
Requirements
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
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.
