packets. By limiting the traffic rate based on flows, the S1720 implements line-speed forwarding
on each interface to ensure high quality of the voice, video, and data services. Each interface
supports eight queues and multiple queue scheduling algorithms such as WRR, SP, and WRR
+SP.
Powerful Surge Protection Capability
The S1720 adopts a Huawei patented surge protection technique to prevent lightning induced
overvoltage. All interfaces of the S1720 have a surge protection capability of 6 kV. The Huawei
patented surge protection technique greatly reduces the possibility of lightning damages on the
equipment even in atrocious environments or in scenarios where grounding cannot be
implemented.
Energy-Saving Design
The S1720 uses an energy-saving integrated circuit design to ensure even heat dissipation. Idle
ports can enter the sleep mode to further reduce power consumption. The S1720 generates no
noises because it does not have any fans. Radiation of the S1720 is within the range of radiation
standards for electric appliances and has no harm to the human body.
