PA-7050 PAN-AIRDUCT INSTALLATION
START
Parts List
Introduction
The PAN-AIRDUCT kit converts the PA-7050 next-generation
firewall chassis cooling from side-to-side airflow to front-to-back airflow (Figure 1). The kit will increase the rack unit (RU) size from 9U
to 14U.
For detailed information about the PA-7050 hardware, refer to the
PA-7050 Hardware Reference Guide and the PA-7050 Quick Start
at https://paloaltonetworks.com/documentation (Platforms section).
The following lists the contents of the PAN-AIRDUCT kit:
Main Components
• PA-7050 PAN-AIRDUCT Installation Document
• Air Duct – (1 each) top air duct and (1 each) bottom air duct used to redirect
airflow
• 2-Post rack bracket – (2 each) used to attach the assembled air duct kit and
chassis to a 2-Post rack
• 4-Post adjustable rack rail – (4 each) used to attach the assembled air duct
kit and chassis to a 4-Post rack. You must slide the rear part of the rack rail
off of the front part of the rail during the installation.
• Rear Brackets – (2 each) used to secure the rear of the chassis to the air
ducts in a 2-Post or 4-Post installation. Note, one side of the bracket has 10
holes, 5 of which are used to secure the bracket to the chassis. Use the 5
holes that line up with the holes in your chassis.
• ESD Wrist Strap – used to prevent electrostatic discharge when handling
removable components.

PA-7050 PAN-AIRDUCT Parts
The 2-Post and 4-Post installations require that the existing chassis brackets are in the
front mount position (Figure 2) and that the rear chassis brackets are removed. During the
PAN-AIRDUCT installation, you will use theses brackets to secure the chassis to the air ducts. If a cable
management bracket is installed on the chassis, ensure that the bracket is installed in the top position,
so the cables do not block the bottom air intake. Note that you must use the cable management bracket
with the 90-degree angle. For more information on the chassis brackets and cable management bracket,
see the PA-7050 Quick Start or PA-7050 Hardware Reference Guide.

IMPORTANT
• Read this entire document before performing the installation.
• Power off the PA-7050 firewall, disconnect all cables, and remove the chassis from the rack or cabinet
before proceeding. To reduce the overall weight of the chassis (recommended), remove NPCs, the
LPC, SMC, fan trays, and power supplies. If you are
removing components, make note of their locations.
• Ensure that the front and rear of the rack/cabinet are
unobstructed to ensure proper front-to-back airflow.
• Perform this procedure using two to three people
and a mechanical lift.
• If you remove any of the removable components to
reduce the weight of the chassis, you must do so on
an ESD protected surface and you must wear the
provided ESD wrist strap connected to a grounding
point.

1. Ensure that the existing PA-7050 chassis brackets are in
the front-mount position (Figure 2).
When installing groups of screws for a given component, insert each screw first and partially tighten to ensure
the screws are properly aligned. You can then fully tighten
based on the torque specified in the Parts list.
2. Place the bottom air duct on a sturdy flat surface with the
front air intake ducts facing you.
3. While facing the front of the PA-7050 firewall, carefully
rotate the chassis 90 degrees to the right (clockwise) and
lay it on its side (power supplies on the left) and then place
the chassis on top of the bottom air duct. Be careful not
to damage the gasket located between the chassis and air
duct.
4. Place the top air duct, with the exhaust vents facing the rear
of the rack, on top of the chassis (Figure 3).
5. Secure the top and bottom chassis brackets located at the
front of the chassis to the air ducts, using four 10-32 X .750
Phillips Pan Head screws for the top bracket and four 10-32
X .750 screws for the bottom bracket (Figure 4).
6. Attach the 2-Post brackets to each side of the air ducts
(one left one right) using six 8-32 X .375 Phillips Pan Head
screws at each mount point. Each mount point uses three
screws inserted into the fixed holes and three screws
inserted into the adjustable holes( Figure 4).
7. Attach the top and bottom rear brackets that secure the
rear of the chassis to the top and bottom air ducts. Each
rear bracket uses five M4 X 8mm screws to secure the rear
bracket to the chassis and four 10-32 X .750 screws to secure the rear brackets to the air duct (Figure 5).
8. Fully tighten the 2-Post bracket screws, chassis bracket
screws, and rear bracket screws to the torque specified in
the Parts List.
9. Using two to three people (mechanical lift recommended),
position the assembled unit into the 2-Post rack and then
secure the rack brackets to the rack using eight 12-24 X
.750 or 10-32 X .750 Phillips Pan Head screws (depending
on the rack thread type) per side (Figure 6). If the rack has
square holes, use the 10-32 screws and 10-32 cage nuts.
10. If you removed any of the front-slot components from the
chassis, reinstall them and then reconnect cables and power-on the chassis.

5.
When installing groups of screws for a given component, insert
each screw first and partially tighten to ensure the screws are properly aligned. You can then fully tighten based on the torque specified
in the Parts list.
Attach the top and bottom rear brackets that secure the rear of the
chassis to the top and bottom air ducts. For this step, only attach
the rear brackets to the PA-7050 firewall chassis using five M4 X
8mm screws (Figure 10). You can perform this step after installing
the air ducts, but the screws that secure the rear brackets to the
chassis may be difficult to install if the device is located at the very
top or bottom of the rack.
Remove the rear section of each 4-Post rack rail by sliding the rear
rail away from the front rail. The rear part of the rail will be installed
after you install the air ducts into the 4-Post rack.
Attach the front part of the 4-Post rack rail to the sides of the top
and bottom air ducts. Each air duct requires one 4-Post rack
rail on each side (4 total), each secured with six 8-32 X .375 Phillips
Pan Head screws (Figure 7).
Install the bottom air duct (with the air intake at the front) into
the 4-Post rack by securing the front of the rack rails using
four 12-24 X .750 or 10-32 X .750 Phillips Pan Head screws (depending on the rack thread type) to each of the two mount points
of the rack (Figure 8). From the rear of the rack, slide the rear part
of the rack rails into the front part of the rail and secure to the rack
using the same number and type of rack mount screws. If the rack
has square holes, use the 10-32 screws and 10-32 cage nuts.
IMPORTANT: Before installing the chassis on the bottom mounted
air duct, ensure that all rack mount screws are properly installed and
tightened based on the torque specified in the Parts List.
A properly installed bottom air duct can temporarily support the
chassis.
6. While facing the front of the PA-7050 firewall, carefully rotate the
chassis 90 degrees to the right (clockwise) and lay it on its side
(power supplies on the left) and then place the chassis on top of the
bottom air duct (Figure 9). Ensure that the rear brackets hang over
the rear of the bottom air duct. Be careful not to damage the gasket
located between the chassis and air duct.
7. Secure the bottom chassis bracket to the air duct using four 10-32 X
.750 Phillips Pan Head screws (Figure 9).
8. Place the top air duct on top of the chassis and then slide the rear
part of the 4-Post rack rail into the front part of the rail.
9. Secure the rack rails to the rear of the rack using four 12-24 X .750
or 10-32 X .750 Phillips Pan Head screws (depending on the rack
thread type) to each of the four mount points of the rack (Figure 10).
If the rack has square holes, use the 10-32 screws and the 10-32
cage nuts.
10. Secure the upper chassis brackets to the top air duct using four 1032 X .750 Phillips Pan Head screws (Figure 10).
11. Install the remaining rear bracket screws to the back of the
top and bottom air ducts using four 10-32 X .750 screws
(Figure 10).
12. If you removed any of the front-slot components from the chassis,
reinstall them and then reconnect cables and power-on the chassis.
