Product overview
Introduction
H3C S5120-SI Switch Series is a line of Layer 2 Gigabit Ethernet switching products developed by
Hangzhou H3C Technologies Co., Ltd. (hereinafter referred to as H3C). The S5120-SI switches are
intelligent manageable switches designed for network environments where high performance,
high-density port distribution, and easy installation are required.
With 10/100/1000 Mbps Ethernet interfaces, the S5120-SI switches are mainly deployed at the access
layer in enterprise networks requiring Gigabit to the Desktop (GTTD) application and at the distribution
layer in metropolitan-area networks (MANs). In the latter deployment, the S5120-SI Switch Series
provides GE electrical interfaces for user access or low-end switch convergence in the downlink direction.
In the uplink direction, they are aggregated to large-capacity Layer 3 switches or switches at the
exchange office through their GE interfaces.
Table 1 and Table 2 show the models and system specifications of the S5120-SI Switch Series.
