Install the PA-220 Firewall Using the PAN-PA-220-RACK-SINGLE

1. Align the back of the firewall with the two tabs located on the rack mount.

2. Use two #4-40 X 1/4” screws to attach the back of the firewall to the two tabs from Step 1. Use two more #4-40 X 1/4” screws to attach the left and right sides of the firewall to the front mounting ears.

3. Secure the power supply in the rack mount.
   1. Place the power supply under the mount’s left or right slot with the DC power cable extending towards the walled side of the mount.
   2. Draw the DC connector around to the back of the firewall and plug it into the PWR 1 port.
   3. Use a cable tie to coil any excess length of wire and loop the tie through the nearby latch feature on the mount.
   4. Use one #4-40 X 1/4” screw to install the provided bracket over the power supply. The bracket should encase and lock the power supply in place, as shown in the image below.
   5. Draw the AC power supply cable out the back of the mount. Assess the distance from the firewall to the power source and coil any excess length of wire as needed. Do not connect the AC power supply cable to the power source yet.

4. (Optional): Install a second power supply for redundancy. Repeat Step 3 using the opposite mount slot and the PWR 2 port.
5. Install the firewall onto the 19-inch rack frame and secure it with four #10-32 X 3/4” or #12-24 X 1/2” screws. Torque the #10 screws at 25.0 in-lbs and the #12 screws at 32.0 in-lbs.

6. Plug the AC power supply cable(s) into a power source.
