Exhaust fans trays
Two fan trays that provide ventilation and cooling for the firewall. Each fan tray contains four fans and a status LED.
While facing the back of the firewall, fan tray 1 is on the left and fan tray 2 is on the right.
Do not use the fan tray handles to lift or move the firewall.
PWR 1 and PWR2
Use the power supply inputs (either AC or DC) to connect power to the firewall.
While facing the back of the firewall, PWR 1 is on the left and PWR 2 is on the right.
Use the two-post ground stud to connect the firewall to earth ground. The firewall ships with a 6AWG two-hole ground lug attached to the ground studs, but does not include a ground cable.
