1 Product Overview

Overview

H3C S5120-EI Series Ethernet switches (hereinafter referred to as S5120-EI series) are Gigabit

Ethernet switching products developed by H3C. The S5120-EI series are designed to operate at the

convergence or access layer of enterprise networks and metropolitan area networks (MANs).

Supporting IPv4/IPv6 dual stack, the S5120-EI series provide abundant service features.

The S5120-EI series support the H3C-specific cluster management function, which facilitates your

network management. The S5120-EI C series switches support the Intelligent Resilient Framework

(IRF) technology. You can connect multiple S5120-EI C switches through 10 GE ports to form a logical

entity, thus to establish a new intelligent network with high reliability, expandability and manageability.

The S5120-EI series include six models, and have the system specifications as shown in

Table 1-1.

z You are recommended to use SFP transceivers of H3C on the S5120-EI series.

z The S5120-EI series Ethernet switches support GE SFP transceivers only.

z The types of SFP transceivers may update with time. For information about transceivers, contact

H3C technical support or marketing staff.

z For the models and specifications of each kind of transceivers, refer to H3C Low End Series

Combo Port

Each SFP port and the corresponding 10/100/1000Base-T Ethernet port form a Combo port. For each

Combo port, either the SFP port or the corresponding 10/100/1000Base-T Ethernet port can be used at

a time. For details about the combo port mapping relationship, please refer to

Table 1-5.
