The following procedure describes how to connect
power to a PA-220 firewall.
avoid injury to yourself or damage to your Palo Alto Networks® hardware
or the data that resides on the hardware, read the Product Safety Warnings.
Remove the screw and star washer from the ground
point on the back of the firewall.
Crimp a 14AWG ground cable to a ring lug (cable and lug
not included), place the ring lug over the screw and star washer,
then replace the screw to attach the cable to the firewall. Torque
the screw to 25 in-lbs and then connect the other end of the cable
to earth ground.
Connect the DC connector from the power adapter into
the PWR 1 port on the firewall and tighten the connector nut to
secure the cable to the firewall.
Plug the AC connector from the power adapter into your
AC power source. After power is connected, the firewall powers on
as indicated by the green power LED next to the PWR 1 port. The
front PWR LED shows green when a functioning power adapter is connected.
Connect the DC connector from a second
power adapter (purchased separately) into the PWR 2 port and plug
the AC connector into an AC power source.
Connect the second PA-220 power adapter through a
different circuit breaker to provide power redundancy and to allow
for electrical circuit maintenance.
