1.1 Introduction
This section describes the characteristics of the S3300.
1.1.1 Positioning
WARNING
The Quidway S3300 Ethernet switches are class A products. Customers should take preventative
measures as the operating devices may cause radio interference.
The Quidway S3300 switch (S3300 for short) is a Metropolitan Area Network (MAN) access
device that provides access and data transport functions. The S3300 is developed by Huawei to
meet the requirements for reliable access, aggregation, and high-quality transmission of multiple
services on the MAN . The S3300 functions as the access device or aggregation device of the
MAN. The S3300 provides large capacity, high port density, and cost-effective packet
forwarding capabilities. The S3300 also provides multi-service access capabilities, excellent
extensibility, quality of service (QoS) guarantee, powerful multicast replication, and carrier-
class security, and can be used to build high-reliability ring topologies.
1.1.2 Product Characteristics
Energy-Saving Design
The S3300 saves energy in the following ways:
l
Some models adopt natural heat dissipation, so fans are not required.
NOTE
Currently, the S3328TP-SI/EI adopts natural heat dissipation.
l
The interface chip switches to the power saving mode when an interface is idle, which
means that no peer device is connected to the interface.
l
It uses advanced highly-integrated and energy-saving chips. With the help of the intelligent
device management system, the chips improve system performance and also reduce system
power consumption.
Natural heat dissipation has the following advantages:
l
Product reliability is high.
l
There is no noise pollution.
l
Fans do not need to be maintained periodically, which saves the maintenance cost.
l
The system does not have additional power consumption generated by fans, which improves
the power efficiency.
