Heat, humidity, and a lot of dust might harm your firewall. You should keep it in a well-ventilated environment with temperatures below 80 degrees Fahrenheit to preserve its longevity. If you may not have a bookshelf or rack area where air can freely circulate around the firewall, it can be mounted.
If your web enters the house in an unfavorable place for the firewall, you can run a network cable from that to a suitable site. A few power-related issues must also be addressed. A three-prong outlet will be used to connect your firewall. We recommend using a continuous power supply (UPS) or battery backup to keep Voip and 911 calls operational during a power outage.
