1040.10 and 1040.11.
The following safety warnings apply to all Palo Alto Networks firewalls and appliances, unless a
specific hardware model is specified.
• When installing or servicing a Palo Alto Networks firewall or appliance hardware component
that has exposed circuits, ensure that you wear an electrostac discharge (ESD) strap. Before
handling the component, make sure the metal contact on the wrist strap is touching your skin
and that the other end of the strap is connected to earth ground.
French Translaon: Lorsque vous installez ou que vous intervenez sur un composant matériel
de pare-feu ou de disposif Palo Alto Networks qui présente des circuits exposés, veillez
à porter un bracelet anstaque. Avant de manipuler le composant, vérifiez que le contact
métallique du bracelet anstaque est en contact avec votre peau et que l’autre extrémité du
bracelet est raccordée à la terre.
• Use grounded and shielded Ethernet cables to ensure agency compliance with electromagnec
compliance (EMC) regulaons.
French Translaon: Des câbles Ethernet blindés reliés à la terre doivent être ulisés pour
garanr la conformité de l'organisme aux émissions électromagnéques (CEM).
• (PA-3200, PA-5200, PA-5400, PA-7050, and PA-7080 firewalls only) At least two people are
recommended for unpacking, handling, and relocang the heavier firewalls.
• Do not connect a supply voltage that exceeds the input range of the firewall or appliance. For
details on the electrical range, refer to electrical specificaons in the hardware reference for
your firewall or appliance.
French Translaon: Veillez à ce que la tension d’alimentaon ne dépasse pas la plage d’entrée
du pare-feu ou du disposif. Pour plus d’informaons sur la mesure électrique, consulter la
rubrique des caractérisques électriques dans la documentaon de votre matériel de pare-feu
ou votre disposif.
• Do not replace a baery with an incorrect baery type; doing so can cause the replacement
baery to explode. Dispose of used baeries according to local regulaons.
French Translaon: Ne remplacez pas la baerie par une baerie de type non adapté, cee
dernière risquerait d’exploser. Meez au rebut les baeries usagées conformément aux
instrucons.
• I/O ports are intended for intra-building connecons only and not intended for OSP (Outside
Plant) connecons or any network connecons subject to external voltage surge events.

Before You Begin
•(All Palo Alto Networks appliances with two or more
power supplies)
Cauon: Shock hazard
Disconnect all power cords (AC or DC) from the power
inputs to fully de-energize the hardware.
French Translaon: (Tous les appareils Palo Alto
Networks avec au moins deux sources d’alimentaon)
Débranchez tous les cordons d’alimentaon (c.a. ou
c.c.) des entrées d’alimentaon et meez le matériel
hors tension.
•(PA-7000 Series firewalls only)
Cauon: High touch current
Connect to earth before connecng to the power
supply.
Ensure that the protecve earthing conductor is
connected to the provided ground lug on the rear side
of the firewall.
•(PA-7000 Series firewalls only) When removing a fan
tray from a PA-7000 Series firewall, first pull the fan
tray out about 1 inch (2.5cm) and then wait a minimum
of 10 seconds before extracng the enre fan tray.
This allows the fans to stop spinning and helps you
avoid serious injury when removing the fan tray. You
can replace a fan tray while the firewall is powered
on but you must replace it within 45 seconds and you
can only replace one fan tray at a me to prevent the
thermal protecon circuit from shung down the
firewall.
French Translaon: (Pare-feu PA-7000 uniquement)
Lors du retrait d’un roir de venlaon d’un pare-
feu PA-7000, rerez tout d’abord le roir sur 2,5 cm,
puis paentez au moins 10 secondes avant de rerer
complètement le roir de venlaon. Cela permet aux
venlateurs d’arrêter de tourner et permet d’éviter des
blessures graves lors du retrait du roir. Vous pouvez
remplacer un roir de venlaon lors de la mise sous
tension du pare-feu. Toutefois, vous devez le faire dans
les 45 secondes et vous ne pouvez remplacer qu’un
roir à la fois, sinon le circuit de protecon thermique
arrêtera le pare-feu.

PA-7000 Series Firewall Overview
The PA-7000 Series firewalls (PA-7050 and PA-7080) are high performance modular
firewalls designed for large enterprise and carrier class environments. These mul-
blade chassis can leverage either AC or DC power and have hot-swappable Network
Processing Cards (NPCs) to allow for expansion as needs grow. You can install up to
six NPCs in the PA-7050 firewall and up to ten NPCs in the PA-7080 firewall. These
firewalls also include a dedicated high availability (HA) control port (HA1), as well as
two dedicated 80Gb QSFP HA ports for HA2 (data link) and HA3 (packet forwarding)
funcons. These dedicated HA ports enable PA-7000 Series firewalls to funcon with
full hardware redundancy in either an acve/passive or acve/acve configuraon.
Addionally, to improve logging performance, the firewalls use a dedicated log card to
handle all log processing tasks.
First Supported PAN-OS® Soware Release:
>PAN-OS 6.0—PA-7050 firewall
>PAN-OS 7.0—PA-7080 firewall
The minimum supported PAN-OS soware also varies based on the installed
components. For example, if you install a PA-7000 20GQXM NPC, the firewall
must have PAN-OS 7.1 or later installed. In the PAN-OS 9.0 release, there are also
requirements to install newer components based on the installed hardware. For
example, if you install the PA-7000-100G-NPC in a PA-7050 firewall, you must also
install the PA-7050 second-generaon fan trays (PA-7050-FANTRAY-L-A (le) and
PA-7050-FANTRAY-R-A (right)). For more informaon on these requirements, see
PA-7000 Series Firewall Module and Interface Card Informaon.

1 Exhaust and intake fan
trays (first-generaon fan
tray shown)
Provides venlaon and cooling for the chassis. While
facing the front of the firewall, air enters from the le and
exits to the right.
There are two PA-7050 fan tray models:
PA-7000 Series Firewall Hardware Reference 16 ©2021 Palo Alto Networks, Inc.

PA-7000 Series Firewall Overview
Item Component Descripon
•PA-7050-FAN—First-generaon fan tray. These fan
trays are interchangeable, so you can install them in
either fan tray slot.
•PA-7050-FANTRAY-L-A (le) and PA-7050-
FANTRAY-R-A (right)—Second-generaon fan tray
that provides more cooling capacity than the first-
generaon fan tray. While facing the front of the
firewall, install PA-7050-FANTRAY-L-A on the le and
the PA-7050-FANTRAY-R-A on the right. The right fan
tray also includes the air intake filter that slides into
the fan tray. This fan tray is required when installing
certain hardware components. For example, you must
install this fan tray if you install a PA-7000 100G
NPC. For more details, see the system and hardware
requirements in PA-7000 Series Firewall Module and
Interface Card Informaon.
During normal operaon, the Power LED on the fan tray
is green and the Fault LED is off. If an individual fan fails
on the fan tray, the Power LED turns off and the Fault
LED turns red.
For informaon on replacing a fan tray, see Replace a
PA-7050 Fan Tray.
2 Switch Management Card
(SMC) (first-generaon
SMC shown)
Provides management access to the chassis using a
serial console cable connected to the Console port
or an RJ-45 cable connected to the management
(MGT) port. The SMC also has high availability (HA)
ports and LED indicators that provide informaon on
various chassis components. The SMC also stores PAN-
OS, the configuraon, and management logs (Alarm,
Configuraon, and System).
IMPORTANT: The SMC is required to operate the chassis
and on a PA-7050 firewall, it must be installed in slot 4.
The SMC-B is shipped with four copper 1G
transceivers for use in the MGT-A, MGT-B,
HA1-A, and HA1-B ports. You can use these or
replace them with a transceiver of your choice.
There are two PA-7050 SMC models as described in
PA-7000 Series Firewall Switch Management Cards
(SMCs).
The PAN-OS® soware is preinstalled on the
embedded solid-state drive (SSD) on the SMC.
PA-7000 Series Firewall Hardware Reference 17 ©2021 Palo Alto Networks, Inc.

PA-7000 Series Firewall Overview
Item Component Descripon
3 Air filter Filters air entering the chassis. Periodically inspect the
filter to ensure it is clean. The filter is not designed to be
cleaned and it is recommended that you replace it every
six months (depending on the environment).
If the firewall has the second-generaon fan trays
installed (PA-7050-FANTRAY-L-A on the le and the
PA-7050-FANTRAY-R-A), the air filter is inserted into the
right fan tray (PA-7050-FANTRAY-R-A).
4 Network Processing Card
(NPC)
Provides network connecvity.
On a PA-7050 firewall, you can install up to six NPCs (in
slots 1, 2, 3, 5, 6, and/or 7). You must have at least one
NPC installed before the firewall can process network
traffic.
For more informaon, see PA-7000 Series Firewall
Network Processing Cards (NPCs).
5 Log card
(LPC shown)
There are two log card models that you can install:
•LFC (PAN-OS 9.0 or later)—High-speed log forwarding
card that forwards all dataplane logs to an external log
collecon system, such as Panorama or a syslog server.
The only logs that are stored locally are the Alarm
,Configuraon, and System logs; these logs are stored
on the SMC.
•LPC—Manages and stores all dataplane logs generated
by the firewall. The LPC contains four disk drives that
are configured in two separate RAID 1 pairs to provide
redundancy. Each drive is installed in an Advanced
Mezzanine Card (AMC), which physically connects the
drive to the LPC. When replacing a drive, the AMC and
drives are ordered and installed as one unit.
IMPORTANT: You must have an LFC or LPC installed in
slot 8 for chassis operaon.
