Learn how to connect DC power to a PA-3200 Series firewall.
The following procedure describes how to connect
DC power to a PA-3200 Series firewall with DC power supplies.
power configuration (AC or DC) can be changed in the field. However,
you cannot install both an AC and DC power supply in the same firewall.
The firewall ships with AC power supplies (DC power supplies sold

Remove the two nuts and star washers from the
ground studs on the back of the firewall and then remove the two-post
Crimp a 6AWG ground cable (not included) to the two-post
ground lug and then attach the ground lug to the ground studs on
the firewall. Replace the star washers and nuts and torque to 25
in-lbs. Connect the other end of the ground cable to earth ground.
Power off the DC power sources that
you will connect to the power supplies before you continue to the
Attach the DC power cables (not included) from the DC
power source to the DC power supplies on the back of the firewall.
Remove the plastic DC power input cover
from each of the two DC power supplies and then remove the positive
and negative terminal screws.
Crimp ring lugs to the ends of the positive and negative
DC cables. These lugs are used to connect the DC cables to the DC
inputs on the firewall.
Use the DC terminal screws to connect a positive DC
power cable to the positive terminal on the first DC power supply
and then connect a negative DC power cable to the negative terminal.
Repeat this step for the second DC power supply using separate positive
and negative cables.
Replace the plastic covers over each DC power input.
Connect the two positive and two negative DC power
cables to your power sources and ensure that you observe the correct
polarity (positive to positive and negative to negative).
Connect the second set of power cables
through a different DC circuit to provide power redundancy and to
allow for electrical circuit maintenance.
After all DC power cables are securely connected, power
on the DC power sources. The power supplies powers on, the input
and output LEDs on the power supplies turn green, and the PWR LED
and the power supply LEDs (PWR 1 and PWR 2) on the front of the
firewall turns green.
