Heat Dissipation
The front door, rear door, and bottom plate of the N68E cabinet have high-density air vents.
Therefore, the N68E cabinet supports front air intake, back 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.
Protection Performance
The protection performance of the N68E cabinet is described as follows:
l The cabinet design takes full account of electromagnetic compatibility (EMC). Therefore,
the N68E cabinet has excellent electromagnetic shielding performance.
l The air vents on the bottom plate of the cabinet are installed with air filters. The same
enhances the dust-proof capability of the N68E cabinet.
l The grounding resistance of the N68E cabinet does not exceed 0.1 ohm.
Installation Scenarios
The installation scenarios of the N68E cabinet are as follows:
l The N68E cabinet can be installed on the cement floor.
l The N68E cabinet can also be installed on the antistatic floor. In such a case, the N6X series
supports are required.
Cabinet Combination
The N68E cabinets can be installed side by side. When installing the N68E cabinets side by side,
connect them by using connecting plates, as shown in Figure 1-10.
