1-11 Product OverviewOverviewH3C S5500-EI Series Ethernet Switches (hereinafter referred to as the S5500-EI series) are Layer 3Gigabit Ethernet switching products developed by Hangzhou H3C Technologies Co., Ltd. (hereinafterreferred to as H3C).The S5500-EI series are designed as distribution or access devices for intranets and metropolitan areanetworks (MANs). Supporting IPv4/IPv6 dual stack and 10 GE uplink interfaces, the S5500-EI seriesprovide abundant service features and can also be used for connecting server groups in data centers.The S5500-EI series support the H3C-specific cluster management function, which facilitates yournetwork management. And they also support the Intelligent Resilient Framework (IRF) technology. Youcan connect multiple S5500-EI switches through 10 GE ports to form a logical entity, thus to establish anew intelligent network with high reliability, expandability and manageability.The S5500-EI series include six models, and have the system specifications as shown in Table 1-1.Table 1-1 System specifications of the S5500-EI seriesItem S5500-28C-EI-DCS5500-28C-EIS5500-52C-EIS5500-52C-PWR-EIS5500-28C-PWR-EI S5500-28F-EIPhysicaldimensions(H × W × D)43.6 × 440 × 300 mm(1.72 × 17.32 × 11.81 in.)43.6 × 440 × 420 mm(1.72 × 17.32 × 16.54 in.)43.6 × 440 ×360 mm(1.72 × 17.32 ×14.17 in.)Weight <5 kg (11.02 lb) <7.5 kg (16.53 lb) <6 kg (13.23 lb)Managementport One console port, on the front panel24 ×10/100/1000Base-Tauto-sensingEthernet port4 × 1000Base-XSFP port48 ×10/100/1000Base-Tauto-sensing Ethernetport4 × 1000Base-X SFP port24 ×10/100/1000Base-Tauto-sensingEthernet port4 ×1000Base-XSFP port8 ×10/100/1000Base-T Ethernetport24 ×100/1000Base-X SFP portThe last four 10/100/1000Base-T Ethernet ports and the four SFPports comprise four Combo ports.The last eightSFP ports andthe eight10/100/1000Base-T Ethernetports compriseeight Comboports.GE portsNote: For each Combo port, either the SFP port or the corresponding Ethernet portcan be used at a time.
