Introduction to Product

The H3C S5120-SI Series Ethernet Switches (hereinafter referred to as the S5120-SI series) are Layer
2 Gigabit Ethernet switches developed by Hangzhou H3C Technology Co., Ltd. They 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 series 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 series provide GE
electrical interfaces for user access or low-end switch convergence in the downlink direction. Whereas,
in the uplink direction, they are aggregated to large-capacity Layer 3 switches or switches at the
exchange office through their GE interfaces.
