Product Safety Warnings
To avoid personal injury or death for yourself and others and to avoid damage to your Palo Alto
Networks hardware, be sure you understand and prepare for the following warnings before you
install or service the hardware. You will also see warning messages throughout the hardware
reference where potential hazards exist.
All Palo Alto Networks products with laser-based optical interfaces comply with 21 CFR
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 electrostatic 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 Translation: Lorsque vous installez ou que vous intervenez sur un composant matériel
de pare-feu ou de dispositif Palo Alto Networks qui présente des circuits exposés, veillez
à porter un bracelet antistatique. Avant de manipuler le composant, vérifiez que le contact
métallique du bracelet antistatique 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 electromagnetic
compliance (EMC) regulations.
French Translation: Des câbles Ethernet blindés reliés à la terre doivent être utilisés pour
garantir la conformité de l'organisme aux émissions électromagnétiques (CEM).
• (PA-3200, PA-5200, PA-5400, PA-7050, and PA-7080 firewalls only) At least two people are
recommended for unpacking, handling, and relocating 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 specifications in the hardware reference for
your firewall or appliance.
French Translation: Veillez à ce que la tension d’alimentation ne dépasse pas la plage d’entrée
du pare-feu ou du dispositif. Pour plus d’informations sur la mesure électrique, consulter la
rubrique des caractéristiques électriques dans la documentation de votre matériel de pare-feu
ou votre dispositif.
• Do not replace a battery with an incorrect battery type; doing so can cause the replacement
battery to explode. Dispose of used batteries according to local regulations.
French Translation: Ne remplacez pas la batterie par une batterie de type non adapté, cette
dernière risquerait d’exploser. Mettez au rebut les batteries usagées conformément aux
instructions.
• I/O ports are intended for intra-building connections only and not intended for OSP (Outside
Plant) connections or any network connections subject to external voltage surge events.
WF-500-B Appliance Hardware Reference 9©2023 Palo Alto Networks, Inc.

Before You Begin
•(All Palo Alto Networks appliances with two or more
power supplies)
Caution: Shock hazard
Disconnect all power cords (AC or DC) from the power
inputs to fully de-energize the hardware.
French Translation: (Tous les appareils Palo Alto
Networks avec au moins deux sources d’alimentation)
Débranchez tous les cordons d’alimentation (c.a. ou
c.c.) des entrées d’alimentation et mettez le matériel
hors tension.
•(PA-7000 Series firewalls only)
Caution: High touch current
Connect to earth before connecting to the power
supply.
Ensure that the protective 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 extracting the entire 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 time to prevent the
thermal protection circuit from shutting down the
firewall.
French Translation: (Pare-feu PA-7000 uniquement)
Lors du retrait d’un tiroir de ventilation d’un pare-
feu PA-7000, retirez tout d’abord le tiroir sur 2,5 cm,
puis patientez au moins 10 secondes avant de retirer
complètement le tiroir de ventilation. Cela permet aux
ventilateurs d’arrêter de tourner et permet d’éviter des
blessures graves lors du retrait du tiroir. Vous pouvez
remplacer un tiroir de ventilation 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
tiroir à la fois, sinon le circuit de protection thermique
arrêtera le pare-feu.
