About This Chapter
This chapter describes the N66E and N68E cabinets.
NOTE
lS9300The N68E and N66E cabinets are standard configurations. The cabinets facilitate maintenance
and capacity expansion. In addition, two switches can be located in a cabinet side by side.
lIn this document, the cabinets as shown in Figure of Combined N66E cabinets and Figure of
Combined N68E cabinets are not equipped with side panels. When combining two cabinets, you must
install side panels on the cabinets. Otherwise, heat dissipation of the S9300 is affected.

lThe weight of an empty cabinet consists of the weight of the front door, rear door, and side panels.
1.1.3 Components of the N66E Cabinet
This topic describes the components of the N66E cabinet. N66E cabinets are classified into front-
serviceable cabinets and rear-serviceable cabinets. S9300s use rear-serviceable cabinets. A rear-
serviceable cabinet consists of a front door, a rear door, two side panels, and a rack.
Figure 1-2 show the components of the rear-serviceable cabinet.

1.1.4 Operating Environment of the N66E Cabinet
This topic describes the ambient temperature and relative humidity in the operating environment
of the N66E cabinet.
To ensure long-term reliability of the equipment, the equipment room must have a stable
temperature and humidity. Table 1-2 lists the requirements for the operating environment of the
N66E cabinet.

NOTE
The temperature and humidity of the equipment room refers to the values measured 1.5 m above the ground
and 0.4 m in front of the equipment.
1.1.5 Structural Features of the N66E Cabinet
This topic describes the structural features of the N66E cabinet, including the cabinet material,
cabling mode, heat dissipation, protection performance, ESD jack, installation scenarios, and
cabinet combination.
Cabinet Material
The surface of the cabinet and the rack is purplish grey.
The N66E cabinet is made of welded electro-galvanized steel sheets and cold-rolled steel sheets.
The fireproof performance of the internal materials complies with the Underwriter Laboratories
(UL) standards.
Cabling Mode
Cable apertures are reserved on the top and at the bottom of the N66E cabinet, so that the N66E
cabinet supports overhead cabling and underfloor cabling:
lIn the overhead cabling mode, external cables enter the cabinet through the top of the
cabinet. Figure 1-3 shows the cable apertures.
lIn the underfloor cabling mode, external cables enter the cabinet through the bottom of the
cabinet.
NOTE
S9300 is in the overhead cabling mode.

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
lThe S9300 adopts an air channel from the left to the rear side of the equipment for heat dissipation.
lThe 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:
lThe cabinet design takes full account of electromagnetic compatibility (EMC). Therefore,
the N66E cabinet has excellent electromagnetic shielding performance.
lThe air vents on the bottom plate of the cabinet are installed with air filters, which enhance
the dust-proof capability of the N66E cabinet.
lThe 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
connected properly to the ESD jack in the middle of the N66E cabinet, as shown in Figure
1-4.

Installation Scenarios
The installation scenarios of the N66E cabinet are as follows:
lThe cabinet can be installed on the concrete floor.
lThe cabinet can also be installed on the antistatic floor. In this case, the N6X series supports
are required.
Cabinet Combination
The N66E cabinets can be installed side by side. When installing the cabinets side by side,
connect them by using connecting plates, as shown in Figure 1-5.
Figure 1-5 Combined N66E cabinets
1.2 Introduction to the N68E Cabinet
This section describes the appearance, technical specifications, components, and structural
features of the N68E cabinet.
