Power supply systemAn S5100-48P-EI switch provides AC power input and RPS DC input. The AC and DCpower inputs can be used at the same time, acting as backup for each other.Alternatively, you can use either the AC power input alone or the DC power input alone.Make sure you use an RPS module recommended by H3C as the DC power input.z AC input:Rated voltage range: 100 VAC to 240 VAC; 50 Hz or 60 HzMax voltage range: 90 VAC to 264 VAC; 47 Hz to 63 Hzz DC inputRated voltage range: -48 VDC to -60 VDCMax voltage range: -36 VDC to -72 VDCIV. Cooling systemAn S5100-48P-EI Ethernet switch provides two fans for heat dissipation.1.3.5 S5100-26C-EI Ethernet SwitchI. Front panelAn S5100-26C-EI 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 1-18 shows the front panel of an S5100-26C-EI Ethernet switch.
