Networking Applications

S5100-SI/EI series Gigabit Ethernet switches are designed as convergence layer switches or access
layer switches for enterprise networks and metropolitan area networks (MANs).
S5100-SI/EI series provide 24 or 48 autosensing Gigabit Ethernet ports for connecting downstream
devices. In addition, S5100-26C-EI and S5100-50C-EI also provide two 10GE extension slots to
support flexible networking by means of optional XFP interface cards / XENPAK optical modules /
dedicated stack cards for Gigabit Ethernet to the desktop (GTTD) access of enterprise networks, user
access and convergence of carrier networks, and connection of data center server clusters.
Several typical networking applications are described as follows. (The following applications are for
S5100-EI series.)

Convergence Layer Devices

In medium- and small-sized enterprises or branches of large enterprises, S5100-EI series Ethernet
switches can serve as convergence layer switches that provide high-performance and large-capacity
switching service and support 10GE uplink ports, which provide larger bandwidth for the devices.
S5100-EI series also support abundant QoS features to facilitate users to configure networks with a
variety of features.

Access Layer Devices

S5100-EI series Gigabit Ethernet switches can serve as access layer switches that provide large
access bandwidth and high port density. In addition, S5100-EI series also provide powerful QACL
features to allow users to better design and plan their networks.
