Safety Warnings
Review the cautions and warnings pertaining to the PA-50R Series firewalls prior to
installing the hardware.
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.
- 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.
- Use grounded and shielded Ethernet cables (when applicable) to ensure agency compliance with electromagnetic compliance (EMC) regulations.
- Fiber SFP transceivers emit invisible infrared lasers that can cause significant retinal damage if they make contact with your eyes. As a best practice, power off the device when installing or replacing an SFP module. If handling an SFP module while the device is operating, apply dust caps to the end of the transceiver or make sure to keep it pointed away from your eyes.
- 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.

Caution: Shock hazardDisconnect all power cords (AC or DC) from the power inputs to fully de-energize the hardware.
- Do not connect or disconnect energized DC wires to the power supply.
- The DC supply source must be located within the same premises as the firewall.
- The firewall must be in the same immediate area (such as adjacent cabinets) as any other equipment that has a connection between the earthing conductor of the DC supply circuit and the earthing of the DC system.
- Install all firewalls that use DC power in restricted access areas only. A restricted access area is where access is granted only to craft (service) personnel using a special tool, lock and key, or other means of security, and that is controlled by the authority responsible for the location.
- Install the firewall DC ground cable only as described in the power connection procedure for the firewall that you are installing. You must use the American wire gauge (AWG) cable specified and torque all nuts to the torque value specified in the installation procedure for your firewall.
Radio Antenna Safety Warnings
- Radio Frequency (RF) Radiation Exposure Warning: Hazardous Radiation Exposure Warning—Adjustments or procedures other than those specified may result in hazardous RF radiation exposure. A minimum distance of 20cm (7.87in) must be maintained between the operating radio antennas and personnel.
- Antenna Installation Warning: To avoid hazardous RF radiation exposure, ensure the device is switched off when installing or changing antennas.
- Cellular Devices: The USB 2.0 port on the cellular device is used for maintenance only.
