Understanding the SRX320 Services Gateway Cooling System
The cooling system for the SRX320 Services Gateway includes two fixed fans. The fans
draw air through vents on the front of the chassis and exhaust the air through the back
of the chassis. The airflow produced by the fans keeps device components within the
acceptable temperature range.
Figure 4 on page 13 shows the airflow through the chassis.
