Power supply

AC

Rated voltage: 100 V AC to 240 V AC, 50/60 Hz

Input voltage: 90 V AC to 264 V AC, 47/63 Hz

DC

Rated voltage range: 10.8 V DC to 13.2 V DC

Rated voltage range: -52 V DC to 55 V DC

The S5500-28C-PWR-SI/S5600-52C-PWR-SI must use the external PoE PSU recommended by H3C as its DC input, but not the -48V DC power supply generally available in the equipment room. Otherwise, the device may be damaged.

DC input of the PoE power module:

Rated voltage: –53.5 V

Max voltage range: –52 to–55 V

Maximum power consumption

S5500-28C-SI: 80 W

S5500-52C-SI: 120 W

S5500-28C-PWR-SI: 455 W:

System power consumption 85 W and PoE power consumption 370 W

S5500-52C-PWR-SI:

When no remote power supply RPS is connected, full-load power consumption is 500 W including system power consumption 130 W and PoE power consumption 370 W.

When an RPS is connected, full-load power consumption is 870 W including system power consumption 130 W and PoE power consumption 740 W.
