3.1 Heat Dissipation Mode
This section describes the heat dissipation modes of the S5300.
The heat dissipation system ensures that the S5300 operates at a normal temperature. The
operating temperature of the S5300 is the long-term operating temperature in 1.6 Physical
Specifications.
The heat dissipation system of the S5300 can be in the following modes:
l Natural heat dissipation
l Intelligent heat dissipation
l Forcible heat dissipation
Table 3-1 provides the S5300 models corresponding to each heat dissipation mode.

NOTE
The fans can work in the intelligent mode or forcible mode.
In the intelligent mode, the fans start to operate only when the ambient temperature goes higher than a
specified value.
The following table describes the air circulation through the S5300 chassis.
