55Heat dissipationHeat dissipation is measured in BTU/h, and 1 W equals 3.4121 BTU/h.The heat dissipation of a switch depends on its power consumption. To calculate heat dissipation ofthe switch, assume 90% power consumption is converted to heat, and the efficiency of the powermodule is 90%. Heat dissipation/hour of the switch is 0.9 × (total power consumption of the cardsplus power consumption of the fan tray)/0.9 × 3.4121.For the power consumption of the cards and fan trays of the S9800 Switch Series, see "Powerconsumptions."Temperature and humidityTable 14 Temperature and humidity specificationsItem Operating environment Non-operating environmentTemperature 0°C to 40°C (32°F to 104°F) –40°C to +70°C (–40°F to +158°F)Relative humidity(noncondensing) 5% to 95% 5% to 95%NoiseThe switch fan trays can automatically adjust the fan speed based on the heat dissipation conditionof the switch. The sound pressure levels of the switch vary by fan speed.
