SAGEM 3P@C

To satisfy the requirement for long-term equipment operating temperature, the general chassis design of 3P@C 4450E fully considers the system heat dissipation. When a single device is operating, the heat dissipation of the system is shown in Figure 2-8, where, the air is led in from the lower part and led out from the upper part in the chassis front. The air outlet is on the top of the switch.

Figure 2-8 Heat dissipation of a single system

Hot air is discharged

Cold air comes in

On the air deflector frame is a fan module with 6 radiator fans built in. When the fans are started, the cold air is drawn in from the inlet on the front of the air deflector frame, then goes upward in the cabinet. It passes by the switch, and takes away the heat of the switch, and finally goes out from the top of the switch.

When multiple switches operate at the same time, the hot air in the lower switch are let out from the top of the switch, and exhausted via the rear outlet of the air deflector frame above it. The following figure shows the air ducts in the cabinet in the case that multiple switches are operating at the same time.

Figure 2-9 Air ducts inside the cabinet

The radiator fans are used for cooling and heat dissipation to improve the temperature features of the system and ensure the normal operation of the switch. Make sure these ventilation holes are not blocked and enough space is reserved on two sides of the equipment for air circulation, ventilation and heat

Warning dissipation. Otherwise, if the components in the equipment are overheated, the system would not work normally or even the components would be damaged by overheat.
