1-11 Product OverviewOverviewH3C S5820X Series Ethernet Switches (hereinafter referred to as the S5820X series) are 10-GigabitEthernet switching products developed by Hangzhou H3C Technologies Co., Ltd. (hereinafter referredto as H3C). The S5820X series provide abundant service features. They provide the IPv6 forwardingfunction and GE interfaces. Through H3C-specific cluster management, you can streamline networkmanagement. The S5820X series are designed as distribution or access devices for intranets andmetropolitan area networks (MANs). Supporting IPv4/IPv6 dual-stack, the S5820X series provideabundant service features and routing functions and can also be used for connecting server groups indata centers.The S5820X series support the innovative Intelligent Resilient Framework (IRF) technology. With IRF,multiple S5820X switches can be interconnected as a logical entity to form a new intelligent networkfeaturing high availability, scalability, and manageability. The S5820X series support H3C OpenApplication Architecture (OAA) platform. To enable features such as firewall, anti-virus, IPS, andwireless access control on the switches, you only need to insert OAP cards into the switches andconfigure these features on the OAP cards.The H3C S5820X series include the following two models, and have the system specifications asshown in Table 1-1.z S5820X-28Sz S5820X-28CTable 1-1 The S5820X series system specificationsItem S5820X-28S S5820X-28CDimensions (H × W × D) 43.6 × 440 × 427 mm (1.72 ×17.32 × 16.8 in.)86 × 440 × 467 mm (3.39 × 17.32 × 18.39in.)Weight ≤ 8.5 kg (18.74 lb) ≤ 17 kg (37.48 lb)Console port 1 1Management Ethernetport 1 —USB interface 1 110/100/1000Base-TEthernet ports 4 4SFP+ interfaces 24 14Number of supportedinterface cards — 2
