III. Power Supply System
The S5500-52C-PWR-SI Ethernet switch supports both AC input and DC 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.
AC power 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
The S5500-52C-PWR-SI Ethernet switch supports only the external PoE power supply
recommended by H3C as the DC power. –48 V DC power cannot be used directly.
Otherwise, the device may be destroyed.
DC input:
Rated voltage range: –52 VDC to –55 VDC
IV. Cooling System
The S5500-52C-PWR-SI Ethernet switch provides six fans for heat dissipation.
