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
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

After you determine the power requirements for your firewall, see
and select the topic for your model and power type.
Connect AC Power to a PA-7050 Firewall
The following procedure describes how to connect power to a PA-7050 firewall with AC power
supplies installed. The power supplies require 120VAC 15-amp or 240VAC 20-amp power input.

Put the provided ESD wrist strap on your wrist ensuring that the metal contact is touching
your skin. Then attach (snap) one end of the ground cable to the wrist strap and remove the
alligator clip from the banana clip on the other end of the ESD grounding cable. Plug the
banana clip end into one of the ESD ports located on the front of the chassis before handling
ESD sensitive hardware. For details on the ESD port location, see
STEP 3 |
Ensure that all AC power switches are in the off position.
