Noise
The S7500E series switches adopt different types of fan trays. The S7503E-S adopts fans with a fixed
speed (the fan speed does not change with the heat dissipation volume), so the sound pressure level of
the switch is fixed. The other models adopt fans with the automatic speed adjustment function, so the
sound pressure levels are different when the fan speeds are different. For more information, see Table 36.
