•
"Hardware Cautions" on page 13
•
"Hardware Warnings" on page 13

Hardware Cautions

•
Disconnect the power cord before servicing the PA-500.
•
Shielded Ethernet interface cables should be used to ensure agency compliance with
electromagnetic emissions (EMC). Connecting a PoE enabled port to the firewall is not
recommended because the system does not support the PoE operating mode.
•
To prevent damage from electrical surges, use a Uninterruptible Power Supply (UPS) and
implement the facilities lightning protection requirements outlined in the National Fire
Protection Association (NFPA) 780: Standard for the Installation of Lightning Protection
Systems (or similar effective measures per local regulations).

Hardware Warnings

•
Risk of explosion if the battery is replaced with an incorrect type. Dispose of used
batteries in accordance with government regulations.
