Use the power supply inputs to connect AC or DC power to the firewall. The second power supply is
for redundancy. When facing the back of the firewall, PS1 is on the
right and PS2 is on the left.
When you receive the PA-1400 Series firewall, the PS1 slot has a blank in it that must be removed
before a second power supply (purchased separately) can be
installed for power redundancy.
