Product overview

About the H3C S5820X Switch Series

The H3C S5820X Switch Series is a line of 10-Gigabit Ethernet switching products intended for the

distribution and access layers of enterprise or metropolitan area networks. You can also use this switch

series to offer access to the server farms in a data center.

The H3C S5820X Switch Series offers the following benefits:

• 10-Gigabit ports and a wide range of features, including the routing features, IPv4 and IPv6 dual

stack, and H3C cluster management for streamlined network management.

• Innovative Intelligent Resilient Framework (IRF) technology, which can virtualize connected S5820X

switches into one virtual switch for higher availability, scalability and resiliency, and manageability.

• Support for the H3C Open Application Architecture (OAA). You can install customized open

application platform (OAP) cards in your S5820X switch to provide value-added services including

firewall, anti-virus, IPS, and wireless access control.
