H3C S5120-SI Intelligent GE Switch
Overview
The H3C S5120-SI series switches are Layer 2 intelligent manageable
switches designed for networks where high performance, high-density
port access and easy installation are required. The S5120-SI series
switches are mainly deployed at the access layer in enterprise
Protocol/Rapid Spanning Tree Protocol/Multiple Spanning Tree
Protocol). The STP/RSTP features also support BPDU guard and Root
guard. Thus the redundancy back-up and error tolerance capability of
the link can be greatly improved to guarantee network stability.
networks that require Gigabit to the Desktop (GTTD) and at the
S5120-SI series switches support link-aggregation (including manual
distribution layer in metropolitan-area networks (MANs).
link aggregation and LACP), providing a simple and cost efficient way
The H3C S5120-SI series switches include the following models:
S5120-9P-SI, S5120-20P-SI, S5120-28P-SI, S5120-52P-SI, S51209P-PWRSI, S5120-9P-HPWR-SI, S5120-28P-PWR-SI and S512028P-HPWR-SI.
Features
Full wire-speed, multi-layer switching
S5120-SI series switches offer L2 wire-speed switching capacity. The
product series offers high density, wire speed, GE ports and satisfies
the most demanding requirements. S5120-SI series switches are able
to expand the bandwidth of a switch port and balance the traffic among
all the ports in a link aggregation. This also enhances connection
reliability.
Comprehensive security control policies
S5120-SI series switches support 802.1x authentication to identify
users who attempt to access the network. With the 802.1x client
version checking function enabled, the switch checks the version and
validity of the 802.1x client running on supplicant systems to prevent
those that use earlier versions of the 802.1x client or illegal clients
from logging in.

S5120-SI series switches provide Guest VLAN functions so that

corresponding priority.

Networking Application
In the access layer of large enterprise/campus network
In a large enterprise or campus network, the S5120-SI series switches are located at the access layer. S5120-SI series switches can provide
1000Mbps speed connection directly to the desktop user via the GE ports. S5120-SI series switches use MSTP and LA for reliability and 802.1x for
secure user access. The whole solution provides a cost effective GE-to-Desktop application for customers.
