PA-7000 Series Firewall Installation
Determine PA-7000 Series Firewall Power Configuration
Requirements
The number of active power supplies required to operate a PA-7000 Series firewall depends on
the power input that you connect to the power supplies (120VAC, 240VAC, or -48VDC), the
number of Network Processing Cards (NPCs), and your power redundancy requirement.
To determine the number of active power supplies required to operate the chassis, refer to
PA-7000 Series Power Supply Chart
and locate your model and power input type and then locate
the column that coincides with the number of installed NPCs. 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 chassis and installed
NPCs will still function.
If you connect 120VAC power and you install five or six NPCs in a PA-7050 firewall or ten
NPCs in a PA-7080 firewall, you can configure only partial redundancy. Full redundancy
is not possible because the chassis do not hold twice the minimum number of active
120VAC power supplies required to power the chassis and the NPCs.
