Power Supply Slot Configuration

2200 W DC and 3000 W AC modules can be used together in a switch.

The S9300X-4 provides slots PWR1 to PWR4 for power modules, as shown in Figure 4-14.

The S9300X-4 series switches support three redundancy modes of power modules: N+N, N+1, and N+0. The value of N depends on the maximum power actually required by the system. Ensure that the total maximum output power of N power modules (N x maximum output power of each power module) is larger than the maximum power actually required by the system. For example, the maximum power required by the system is 4000 W. If two 2200 W power modules are installed in the chassis, they work in 2+0 mode. If three 2200 W power modules are installed, they work in 2+1 redundancy mode. If four 2200 W power modules are installed, they work in 2+2 redundancy mode. The system can identify the power redundancy mode, and you do not need to manually configure the power redundancy mode. Table 4-12 describes the three power redundancy modes and the specific redundancy modes supported by the S9300X-4 series switches.

Table 4-12 Description of power redundancy modes

Redundancy Mode	Description	Product Support
N+N	System power supply is not affected if no more than N power modules are removed or fail. The maximum output power of the system is the total maximum output power of N power modules. The first N represents mandatory power modules, and the second N represents optional power modules. NOTE: The N+N redundancy mode is often used when two power supply systems are available. In this case, the first N represents mandatory power modules for the first power supply system, and the second N represents mandatory power modules for the second power supply system. The use of double power supply systems provides redundancy for both power modules and power supply systems. If the device consumes little power and is equipped with multiple power modules, the number of standby power modules may exceed that of active power modules. For example, the power modules work in 1+2 or 1+3 backup mode.	1+1 and 2+2 redundancy
N+1	System power supply is not affected if one power module is removed or fails. The maximum output power of the system is the total maximum output power of N power modules. N power modules are mandatory, and one power module is optional.	1+1, 2+1 and 3+1 redundancy
N+0 (no redundancy)	System power supply is affected once any power module is removed or fails. The maximum output power of the system is the total maximum output power of N power modules. N power modules are mandatory, and there are no optional power modules.	1+0, 2+0, 3+0, and 4+0

When using the N+N redundancy mode, equally divide the power modules into two groups and connect the two groups of power modules to two independent power supply systems. This configuration provides redundancy of power supply systems to enhance system reliability.
If the system power consumption exceeds 50% of a single power module's power, all power modules equally share the power consumption. This reduces the load of a single power module and improves the system reliability.

The following describes the power module configuration for an S9300X-4 switch with different power supplies:

If DC power input is provided, configure power modules according to DC power input.
If 220 V single-phase AC input or 110 V dual-live-wire AC input is provided, configure power modules according to AC power input (220 V single-phase or 110 V dual-live-wire input).
If 110 V single-live-wire AC input is provided, configure power modules according to AC power input (110 V single-live-wire input).

DC power input

Table 4-13 describes the power module configuration for the S9300X-4 series switches when DC power input is provided.

Table 4-13 Power module configuration (DC power input)

Power Module Type	Redundancy Mode	Maximum Output Power
2200 W DC power module	N+N	A maximum of 4 (2+2) 2200 W DC power modules can be configured, providing a maximum output power of 4400 W.
	N+1	A maximum of 4 (3+1) 2200 W DC power modules can be configured, providing a maximum output power of 6600 W.
	N+0 (no redundancy)	A maximum of 4 (4+0) 2200 W DC power modules can be configured, providing a maximum output power of 8800 W.

AC power input (220 V single-phase or 110 V dual-live-wire input)

If the input voltage is 110 V, the dual-live-wire input mode is recommended. In this case, the maximum output power of a 3000 W AC power module is 3000 W.

Table 4-14 describes the power module configuration for the S9300X-4 series switches when 220 V single-phase or 110 V dual-live-wire AC power input is provided.

Table 4-14 Power module configuration (220 V single-phase or 110 V dual-live-wire AC power input)

Power Module Type	Redundancy Mode	Maximum Output Power
3000 W AC power module	N+N	A maximum of 4 (2+2) 3000 W AC power modules can be configured, providing a maximum output power of 6000 W.
	N+1	A maximum of 4 (3+1) 3000 W AC power modules can be configured, providing a maximum output power of 9000 W.
	N+0 (no redundancy)	A maximum of 4 (4+0) 3000 W AC power modules can be configured, providing a maximum output power of 9000 W.

AC power input (110 V single-live-wire input)

When 110 V single-live-wire AC power input is provided, the maximum output power of a 3000 W AC power module is 1500 W. In this case, it is recommended that you use the N+1 or N+0 redundancy mode to increase the maximum output power of the system.

Table 4-15 describes the power module configuration for the S9300X-4 series switches when 110 V single-live-wire AC power input is provided.

Table 4-15 Power module configuration (110 V single-live-wire AC power input is provided)

Chassis Model	Power Module Type	Redundancy Mode	Maximum Output Power
S9300X-4	3000 W AC power module	N+N	A maximum of 4 (2+2) 3000 W AC power modules can be configured, providing a maximum output power of 3000 W.
		N+1	A maximum of 4 (3+1) 3000 W AC power modules can be configured, providing a maximum output power of 4500 W.
		N+0 (no redundancy)	A maximum of 4 (4+0) 3000 W AC power modules can be configured, providing a maximum output power of 6000 W.

Heat Dissipation

It is recommended that you replace the air filter of a device every six months.

The cooling system of an S9300X-4 chassis consists of fan modules behind the air exhaust vent (rear of the chassis) and air filters at the air intake vent (left side of the chassis).

The S9300X-4 has two fan modules respectively, located at the rear of the chassis. The fan modules absorb airflow to exhaust the heat generated by cards and other modules out of the chassis, ensuring that the chassis works in a normal temperature range. For the performance and attributes of fan modules, see Fan Module.
Air filters on a chassis prevent dust from entering the chassis with the airflow.

The S9300X-4 uses a multi-zone cooling system design. If there are empty slots in a zone, the fans in this zone run at a low speed to reduce power consumption and noises.

As shown in Figure 4-16, the S9300X-4 has two fan zones, with four cards in each zone.

Airflow

The S9300X-4, S9300X-8, S9303, S9306, and S9312 have the same airflow for heat dissipation. The S9306 is used as an example to describe the airflow.

The S9300X-4 chassis uses a left-to-back airflow design. Air is absorbed into the chassis from the left side and exhausted out of the chassis from the rear.

Air Filter

The switches may use honeycomb air filters or non-honeycomb air filters. The switches with honeycomb air filters installed in all air filter slots comply with Federal Communications Commission (FCC) standards.

An S9300X-4 switch requires one S9300X-4 air filter.

Figure 4-18 shows a non-honeycomb air filter for the S9300X-4.
