Power Supply SystemThe S5500-52C-SI Ethernet switch supports both AC input and RPS 12 V input. TheAC input and DC input can be used together to serve as backup for each other. Inaddition, either of them can be used alone. You can use only the RPS power supplyrecommended by H3C for DC input.AC power input:Rated voltage range: 100 VAC to 240 VAC, 50 Hz or 60 HzInput voltage range: 90 VAC to 264 VAC, 50 Hz or 60 HzRPS (DC) input:Rated voltage range: 10.8 VDC to 13.2 VDCIV. Cooling SystemThe S5500-52C-SI Ethernet switch provides four fans for heat dissipation.1.2.3 S5500-28C-PWR-SI Ethernet SwitchI. Front PanelThe S5500-28C-PWR-SI Ethernet switch provides 24 × 10/100/1000Base-T Ethernetports, four Gigabit SFP Combo ports and one Console port on the front panel. Figure1-5 shows the front panel appearance of the S5500-28C-PWR-SI Ethernet switch.
