III. Power Supply System
The S5500-28C-SI Ethernet switch supports both AC input and RPS 12 V input. The
AC input and DC input can be used together to serve as backup for each other. In
addition, either of them can be used alone. You can use only the RPS power supply
recommended by H3C for DC input.
AC input:
Rated voltage range: 100 VAC to 240 VAC, 50 Hz or 60 Hz
Input voltage range: 90 VAC to 264 VAC, 50 Hz or 60 Hz
RPS (DC) input:
Rated voltage range: 10.8 VDC to 13.2 VDC
IV. Cooling System
The S5500-28C-SI Ethernet switch provides four fans for heat dissipation.
