Huawei S9700 Series Switch S9703 Introduction

Huawei S9700 comes in the following models: S9703, S9706, and S9712. In this article, HongTelecom will introduce the Huawei S9703 switches.

S9700 Introduction

The S9700 series core routing switches (S9700 for short) are high-end switches designed for service integration in next-generation campus networks and data centers. Based on Huawei Versatile Routing Platform (VRP), the S9700 switches provide high-performance L2/L3 switching and integrate a range of services, such as MPLS VPN, hardware IPv6, desktop cloud, video conferencing, and wireless access. They also provide a variety of reliability technologies including in-service software upgrade, non-stop forwarding, hardware OAM/BFD, and ring network protection. These improve the network efficiency and maximize the normal operation time, thereby reducing the total cost of ownership (TCO).

The S9700 comes in the following models: S9703, S9706, and S9712. These models support a maximum of 3, 6, and 12 line processing units (LPUs), respectively.

Power Supply Slot Configuration

 NOTE:

If a switch is running a version prior to V200R010C00, it does not allow combining the use of AC and DC power modules or power modules of different wattages. If the switch is running V200R010C00 or a later version, it allows combining the use of 2200 W AC and DC power modules. If the switch is running V200R012C00 or a later version, it allows combining the use of 2200 W AC, 2200 W DC, and 3000 W AC power modules.

The S9703 provides slots PWR1 and PWR2 for DC or AC power modules, as shown in Slot layout on the S9703 chassis (front).

The S9703 series switches support two redundancy modes of power modules: N+N, 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. The system can identify the power redundancy mode, and you do not need to manually configure the power redundancy mode. Table 3 describes the three power redundancy modes and the specific redundancy modes supported by the S9703 series switches.

Table 3 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.	1+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, and 2+0

 NOTE:

• 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.
• When using the N+N redundancy mode, you are advised to install N power modules (as specified by the first N) in the power supply slots at the left side and install N power modules (as specified by the second N) in the power supply slots at the right side. Power slots are marked PWR.
• 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 S9703 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 describes the power module configuration for the S9703 series switches when DC power input is provided.

Table 4 Power module configuration (DC power input)

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

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

 NOTE:

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, the maximum output power of a 2200 W AC power module is 2200 W, and the maximum output power of an 800 W AC power module is 800 W.

Table 5 describes the power module configuration for the S9703 series switches when 220 V single-phase or 110 V dual-live-wire AC power input is provided.

Table 5 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 2 (1+1) 3000 W AC power modules can be configured, providing a maximum output power of 3000 W.
	N+0 (no redundancy)	A maximum of 2 (2+0) 3000 W AC power modules can be configured, providing a maximum output power of 4400 W.
2200 W AC power module	N+N	A maximum of 2 (1+1) 2200 W AC power modules can be configured, providing a maximum output power of 2200 W.
	N+0 (no redundancy)	A maximum of 2 (2+0) 2200 W AC power modules can be configured, providing a maximum output power of 4400 W.
800 W AC power module	N+N	A maximum of 2 (1+1) 800 W AC power modules can be configured, providing a maximum output power of 800 W.
	N+0 (no redundancy)	A maximum of 2 (2+0) 800 W AC power modules can be configured, providing a maximum output power of 1600 W.

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

 NOTE:

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, the maximum output power of a 2200 W AC power module is 1100 W, and the maximum output power of an 800 W AC power module is 400 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 6 describes the power module configuration for the S9703 series switches when 110 V single-live-wire AC power input is provided.

Table 6 Power module configuration (110 V single-live-wire AC power input is provided)

Power Module Type	Redundancy Mode	Maximum Output Power

	N+0 (no redundancy)	A maximum of 2 (2+0) 2200 W AC power modules can be configured, providing a maximum output power of 2200 W.
800 W AC power module	N+N	A maximum of 2 (1+1) 800 W AC power modules can be configured, providing a maximum output power of 400 W.
	N+0 (no redundancy)	A maximum of 2 (2+0) 800 W AC power modules can be configured, providing a maximum output power of 800 W.

Heat Dissipation

 NOTE:

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

The S9703 cooling system consists of fan modules and air filters. A fan module is located behind the air exhaust vent (rear of the chassis), and an air filter is located outside the air intake vent (left side of the chassis).

• The S9703 has one fan module, located at the rear of the chassis. The fan module draws cold air into the chassis to dissipate heat generated by working components, ensuring that the chassis operates within a normal temperature range. For details about the performance and attributes of a fan module, see Fan Module.
• The air filter prevents dust from entering the chassis with the airflow.

Airflow

 NOTE:

The S9703, S9706, and S9712 use the same airflow design.

The S9703 chassis uses a left-to-back airflow design. Cold air is drawn into the chassis from the left side, dissipates heat in the chassis, and is exhausted from the rear of the chassis. Figure 7shows the airflow in the chassis.

Figure 7 Airflow in the chassis

Air Filter

 NOTE:

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.

The S9703 uses either a sponge air filter or a honeycomb air filter. An FCC-certified chassis must use a honeycomb air filter. Figure 8 shows a sponge air filter, and Figure 9 shows a honeycomb air filter.
