PA-5200 Series firewall power connection overview.
PA-5200 Series firewalls have either
two AC or two DC power supplies (the second power supply is for
redundancy). The firewall requires a 100-240VAC (50-60 Hz) or -40
to -60VDC power source, depending on the type of power supplies
installed in the firewall (AC or DC).For more details on power requirements
and power consumption, see
