(hereinafter referred to as H3C). The S5500-EI series support diversifiedservice features, IPv6 forwarding, and routing function, and provide 10GE extendedmodule slots. Through the H3C proprietary cluster management, you can streamlinenetwork management. The S5500-EI series are designed to operate at theconvergence or access layer of enterprise networks and metropolitan area networks(MANs). The S5500-EI series support the IPv4/IPv6 dual stack and can also be usedfor connecting server groups in data centers.Table 1-1 lists the models of the S5500-EI series.Table 1-1 Models of the S5500-EI seriesModelNumber ofauto-sensing10/100/1000Base-TEthernet portsNumber of1000Base-X SFPportsNumberofconsoleportsS5500-28C-EI 24 4S5500-28C-EI-DC 24 4S5500-52C-EI 48 4S5500-28C-PWR-EI 24 4S5500-52C-PWR-EI 48 4S5500-28F-EI 8 241Together with an auto-sensing 10/100/1000BASE-T Ethernet port, each 1000Base-XSFP port forms a Combo port. For each Combo port, either the SFP port or theauto-sensing 10/100/1000BASE-T Ethernet port can be used at a time. For themapping between the two ports forming a Combo port, refer to Table 1-2.Table 1-2 Mapping between two ports forming a Combo portModel 1000Base-X SFPport numberAuto-sensing 10/100/1000Base-TEthernet port number25 2226 24S5500-28C-EIS5500-28C-EI-DCS5500-28C-PWR-EI 27 21
