Heat Dissipation
The front door, rear door, and top plate of the N66E cabinet have high-density air vents.
Therefore, the cabinet supports front air intake, rear air exhaust, and upper air exhaust and
provides good heat dissipation performance.
NOTE
l The S9300 adopts an air channel from the left to the rear side of the equipment for heat dissipation.
l The airflow of S9300 in the cabinet is: front of the cabinet -> left side of the equipment -> inside the
equipment -> rear of the equipment -> rear of the cabinet. This ensures good heat dissipation.
Protective Performance
The protection performance of the N66E cabinet is described as follows:
l The cabinet design takes full account of electromagnetic compatibility (EMC). Therefore,
the N66E cabinet has excellent electromagnetic shielding performance.
l The air vents on the bottom plate of the cabinet are installed with air filters, which enhance
the dust-proof capability of the N66E cabinet.
l The grounding resistance of the N66E cabinet is equal to or lower than 0.1 ohm.
ESD Jack
When wear an ESD-preventive wrist strap, ensure that the connector of the wrist strap is
