Heat dissipation
Heat dissipation is measured in BTU/h, and 1 W equals 3.4121BTU/h.
The heat dissipation of a gateway depends on its power consumption. To calculate heat dissipation
of the gateway, assume 90% power consumption is converted to heat, and the efficiency of the
power module is 90%. Heat dissipation/hour of the gateway is 0.9 × (total power consumption of the
cards plus power consumption of the fan tray)/0.9 × 3.4121.
