Connect Ac Power To A Pa-7050 Firewall - PaloAlto Networks PA-7000 Series Hardware Reference Manual

Model and Power
Input
PA-7080 Firewall
240VAC or -48VDC
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
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
Component Electrical
Series Firewall Power
After you determine the power requirements for your firewall, see
Firewall 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. For details on
power requirements, see
STEP 1 | Read Product Safety
STEP 2 | 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
Front Panel (AC).
STEP 3 | Ensure that all AC power switches are in the off position.
STEP 4 | Remove the two nuts and star washers from the ground studs located on the back of the
chassis on the upper left side.
Crimp a 6-AWG wire to the provided grounding lug and connect the other end to your earth
