Networking Applications
The S5120-SI series are GigabitEthernet switches. They are designed as distribution and access
devices for small- and medium-sized enterprise networks. An S5120-SI switch provides 16, 24, or 48
autosensing downstream GE interfaces, and thus can be used in networking flexibly. For example, the
S5120-SI series can be used for Gigabit to the Desktop (GTTD) access in enterprise networks and
connecting data center server clusters. Several typical networking applications are presented in this
section.
Distribution Layer Switches
In medium- and large-sized enterprises or campus networks, the S5120-SI series Ethernet switches
can serve as distribution layer switches that provide high-performance and large-capacity switching
service.
