Cooling system
For adequate cooling of the firewall, follow these guidelines:
•
Plan the firewall installation position for the airflow direction of the firewall to match the
ventilation designs at the installation site.
•
Reserve a minimum clearance of 80 mm (3.15 in) around the inlet and outlet air vents.
•
Make sure the installation site has a good cooling system.
•
When installing the firewall in a standard 19-inch rack, reserve a distance of 1U (44.45 mm, or
1.75 in) between the chassis and other devices.
The F1000-AI-05 firewall cools itself naturally.
The F1000-AI-15 firewall provides front side-intake and rear side-exhaust airflow for heat dissipation.
The F1000-AI-25, F1000-AI-35, F1000-AI-55, F1000-AI-65, and F1000-AI-75 firewalls provide left
side-intake and right side-exhaust airflow for heat dissipation.
