Power off the DC power sources that you
will connect to the power supplies before you continue.
Verify that the DC power source that will power
the firewall is powered off.
In the following procedure, connect
the DC power cables—and ground cable if you do not use the screw-on
ground point—to the DC terminal block before you attach the DC terminal
block to the firewall.
Connect one end of a 16-22AWG ground cable to the firewall
and connect the other end to earth ground. There are three ground
locations on the firewall: one screw-on ground point above the DC
power inputs and two ground inputs on the DC terminal block (last
two inputs to the right of the DC inputs); use only one of the three
ground locations even if you will connect a second set of DC power
cables for redundancy.
Screw-on ground point (
the ground screw from the screw-on ground point, hold the 6-32 ring
lug (that you previously attached to the ground cable) over the
screw hole, and then re-attach the screw to secure the cable to
the firewall. Do not torque the screw to more than 6 in-lbs.
DC terminal block ground inputs (
cable into one of the two ground input terminals and then secure
the cable by turning the flat-head terminal screw clockwise. Do
not torque the terminal screws to more than 2 in-lbs.
Insert the positive DC cable into terminal A+ and secure
the cable by turning the flat-head terminal screw clockwise until
tight. Insert the negative cable into terminal A- and secure the
cable using the terminal screw. Do not torque the terminal screws
to more than 2 in-lbs.
) Repeat step 3 to connect a second
DC power source to terminals B+ and B-.
Plug the cabled DC terminal block into the DC inputs
on the firewall. Secure the terminal block by turning the two screws
on each side of the block clockwise and torque to 3 in-lbs.
Power on the DC power source to power on the firewall.
The firewall powers on and the power (PWR) LED turns green.
