Product Features
Introduction to Product
The H3C S5120-SI Series Ethernet Switches are intelligent, manageable, Layer 2 Gigabit Ethernet
switches designed for the access and distribution layers of enterprise networks. The series delivers
high performance, high port density, and ease of installation.
The S5120-SI series provides 10/100/1000Base-T auto-sensing Ethernet ports. You can deploy the
switches at the access layer of an enterprise network to implement the Gigabit to the Desktop (GTTD)
solution.
The S5120-SI is also suitable for the distribution layer of a metropolitan-area network (MAN). You can
connect the S5120-SI series to end users or wiring-closet switches through gigabit Ethernet copper
ports, and to Layer 3 switches through gigabit Ethernet fiber-optic ports or link aggregation.
See Table 3-1 for all S5120-SI switch models and their basic hardware specifications.

Network Scenarios
An S5120-SI switch provides 16, 24, or 48 downlink gigabit Ethernet interfaces. You can deploy the
S5120-SI series at the access or distribution layer of a small- and medium-sized enterprise network.
For example, you can use the series to provide gigabit to desktop connections or connecting data
center server farms. This section describes several typical application scenarios for the S5120-SI
series.
