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.

PA-7080 Firewall 240VAC or -48VDC | 1 | 1 | 2 | 2 | 2 | 2 | 2 | 2 | 2 | 3 |
For example, if you have a PA-7080 firewall with ten NPCs and
configure it to use 240VAC or ‑48VDC, you must power on a minimum
of three power supplies to power the chassis and all NPCs. For full
redundancy, you must install and power on two power supplies in
addition to the four that come with your chassis for a total of
six active power supplies.
If one or more power supplies fail and there is not enough power
to operate all installed NPCs, the firewall powers down NPCs starting
from the highest NPC slot number to the lowest NPC slot number until
the hardware power requirements no longer exceed the power that
is still available to the chassis.
The power calculations used to provide the values in Example
Chassis Power Output from a PA-7080 Firewall are based on
the total output of each active power supply (1,200 watts with 120VAC
input or 2,500 watts with either 240VAC or -48VDC input) minus the
rated power consumption of all hardware components. You can find power
information for hardware components in PA-7000
Series Firewall Component Electrical Specifications. To view
power statistics on an active firewall, see View
PA-7000 Series Firewall Power Statistics.
After you determine the power requirements for your firewall,
see Connect
Power to a PA-7000 Series Firewall and select the topic for
your model and power type.
