Installation ManualH3C S5100-SI/EI Series Ethernet Switches Chapter 1 Product Overview1-6V. Cooling systemAn S5100-16P-SI Ethernet switch provides one fan for heat dissipation.1.2.3 S5100-24P-SI Ethernet SwitchI. Front panelAn S5100-24P-SI Ethernet switch provides 24 x 10/100/1000Base-T autosensingEthernet ports, four 1000Base-X SFP ports, and one console port on the front panel. AnSFP port and its corresponding 10/100/1000Base-T autosensing Ethernet port form aCombo port. That is, only one of the two ports forming the Combo port can be used at atime. Table 1-2 shows the mapping relations between the ports forming the Combo port.Figure 1-6 shows the front panel of an S5100-24P-SI Ethernet switch.(1): 10/100/1000Base-T autosensing Ethernet port status LEDs(2): 1000Base-X SFP port status LED (3): Console port(4): 7-segment digitron display (5): Power LED(6): Ethernet port mode switching LED (7): Port status LED mode switchFigure 1-6 Front panel of an S5100-24P-SI Ethernet switchII.
