Cooling fans
The fans decrease the internal temperature of the device. When you connect the Firebox to power,
the fans start at a low speed. When you power on the Firebox, the fan speed increases to
maximum RPM. The device adjusts the fan speed based on the external temperature, CPU load,
and power supply load.
Power switch
Controls the power supplied to the Firebox. The Power switch activates both power supplies.
AC receptacles
Each AC receptacle accepts a detachable AC power cord supplied with the Firebox. Each power
supply is a WatchGuard standard auto-sensing AC power supply.
Replaceable power supplies
There are two power supplies on the Firebox M5800, each with a power indicator at the top.
