Heat dissipation

The heat dissipation of the switch depends on power consumption. To calculate heat dissipation of the
switch, assume 90% power consumption is converted to heat, and the efficiency of the power module is
80%. Heat dissipation/hour of the switch is 0.9 × (total power consumption of the cards plus power
consumption of the fan tray)/0.8 × 3.4121.
NOTE:
For the power consumption of the cards and fan trays of the S7500E series switches, see
•
power consumption and total power
Heat dissipation is measured in the unit of BTU/h. 1 W = 3.4121BTU/h.

When the altitude is 4 km, the highest
operating temperature is 31.8°C
(89.24°F). The maximum operating
temperature increases 0.33°C
(0.59°F)/100 m (328.08 ft) upwards
until 45°C (113°F) is reached.
