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.
Model and Power Input | Front Cards Installed and Active
Power Supplies Required | ||||
|---|---|---|---|---|---|
1 DPC | 2 DPCs | 3 DPCs | 4 DPCs | 5 DPCs | |
PA-5450 Firewall 110/120VAC | 2 | 2 | 3 | 3 | 3 |
PA-5450 Firewall 240VAC
or -48VDC | 1 | 1 | 2 | 2 | 2 |
All power supply requirements in the table above account
for 1 or 2 NCs being installed in the appliance.
You can find power information for PA-5450 hardware components
in PA-5450 Firewall Component Electrical Specifications.
