S7700

Core devices on a network have higher security requirements. If a high volume of attack traffic is sent to a core device, the CPU usage becomes high, which leads to failure in processing control or management packets. The network fails to run properly.

The S7700 supports hardware-based CPU queues to defend against malicious traffic, DDoS attacks, and viruses, ensuring secure running of devices.

The dedicated hardware-based CPU queues of the S7700 can process control or management packets sent to the CPU in a differentiated way. The CPU preferentially processes key services.

management IP addresses, management VLAN IDs,

and network and basic service parameters.

2. Make configuration data: generate a configuration script,

dynamically manage information in the intermediate file, and

configure the commander.

3. Install the device: install a client on an

onsite device and reports the mapping

between its MAC address and installation

position.

4. The switch starts and then sends a DHCP request.

TÜV Rheinland's Green-Mark certificate is a famous certificate difficult to gain.

The Green-Mark certification covers requirements on environmental protection, recycling, energy efficiency, EMC,

safety regulations, carbon footprint, and social responsibility.

The S7700 series (S7703/S7706/S7712) uses multiple energy conservation technologies including environment

monitoring chips, intelligent fan speed adjustment, and left-to-back airflow design. These technologies make S7700

fully satisfy Green-Mark requirements. Source: http://www.tuv.com/news/en/greater_china/about_us_cn/press_3/pressreleases_gc_en/news_content_en_154565.html/Huawei%20S7700%20Series%20Smart%20Routin

Fans adjust their rotation rates based on the temperatures

of line cards and optical modules to minimize power

consumption.

Fans in an idle area, such as a group of slots without line

cards, work at the lowest rate: 30% of full speed and 5 W

power consumption. This reduces noise and prolongs fan

service life.

Cards in different areas are cooled

Unique Left-to-Rear Airflow

• Increases air resistance by 25% as rack sides block

the air. The coefficient of performance (COP) value is

low: only 0 to 20.

• Mixes cold and hot air in the right chassis, causing a

3℃ to 5℃ temperature increase at the air intake.

• Uses low-efficiency fans that have small diameters

and run at a high speed. The fans have limited heat

dissipation capability for slots, make a lot of noise,

and provide low reliability. The system cannot work

properly when one fan module fails.

COP = Chassis Power Consumption/Heat Dissipation Power Consumption

A larger COP value indicates less energy used for dissipating heat and a higher heat dissipation efficiency.

• Optimizes cold and hot air channels in the

equipment room and reduces interference among

devices.

• Reduces air backflow and improves heat

dissipation efficiency. The COP value is higher

than 50.

• Uses high-efficiency fans that have large

diameters and run at a low speed, reduces the

number of fans by more than 30% and noise by 5

dB to 10 dB. The system can still work properly

when one fan module fails.

High-Density Cabling, Saving Space

Traditional switches use left-to-right ventilation channels. Restricted by poor heat dissipation, 48-port cards cannot be

installed in all slots.

The Huawei S7700's left-to-rear ventilation channel design enables the S7712 to be fully configured with high-density cards.

Customer benefits The power-scheduling data network in Zhejiang Province is an

important part of the power system infrastructure and the basis for

implementing automatic scheduling and modern management. The

network ensures secure, stable, and cost-effective operation of the

power grid. Hardware robustness has a direct influence on scheduling

services of the provincial network. This reconstruction project greatly

reduces hardware risks and ensures proper scheduling services for

the provincial network.

Customer requirements During the 10 years since the power scheduling data network in

Zhejiang Province was set up, it has expanded to include devices for

power scheduling across the province and 11 areas. The network

connects to 29 uniform scheduling power plants. During the 10 years,

the power scheduling data network has been reconstructed and

maintained, but performance of multiple devices has degraded and

they require upgrade or replacement.

Huawei solution Replace old devices in 2011 with 2 million CNY worth of new

devices, including 21 NE20-4 routers, 3 NE20E-8 routers, 11

AR3200 routers, 9 S7700 switches, 30 S5700 switches, and 56

S3700 switches.
