Install the PA-400R Series Firewall in an Equipment Rack

1. Slide one of the adjustable mounting brackets into one of the fixed mounting brackets to create a mounting rail. Repeat for the second mounting rail. The adjustable and fixed brackets are the same for the left and right side.

2. Align the bottom edge of the mounting rails to the bottom of the 1 RU (1.5 RU if there is another device above) reserved for your firewall. Align the slotted holes in the adjustable mounting bracket to the holes on the rear of the equipment frame.
   The mounting rails are designed for equipment frames that are 26” to 32” deep.
3. Secure the rails to the equipment frame with mounting screws (not provided) compatible with your equipment frame. Tighten the screws to their recommended torque value.

4. With the front of the firewall facing forward, align the four rubber feet on the bottom of the device to the slotted holes in the provided mounting tray.

5. While holding the firewall, carefully flip the mounting tray over to reveal its underside.
6. Secure the firewall in place using three of the provided #6-32 x 3/16” Long Flathead screws.

7. Flip the mounting tray back into an upright position.
8. Follow the instructions to Connect Power to a PA-400R Series Firewall.
9. Slide the mounting tray into the rails previously fixed to the equipment rack. Stop when the front flange on the mounting tray is flush with the front of the rail.
10. Align the slotted holes in the mounting tray to the holes in the equipment frame. Secure the mounting tray to the equipment frame on both sides using 3 screws each (not provided). The screws must be compatible with your equipment frame.
