Installation Manual
H3C S5100-SI/EI Series Ethernet Switches
Chapter 1 Product Overview
1-23
Voltage range: -52 VDC to -55 VDC
IV. PoE
S5100-50C-PWR-EI Ethernet switches support PoE. They can be connected to remote
PDs, such as IP phones, WLAN APs, Security and Bluetooth APs, over twisted pair
cables to remotely supply -48 VDC power to the connected PDs.
z
When serving as a PSE, an S5100-50C-PWR-EI Ethernet switch supports
IEEE802.3af standards and can also supply power to some of the PDs
incompatible with 802.3af standards.
z
An S5100-50C-PWR-EI Ethernet switch can provide power supplies through its 48
fixed Ethernet electrical ports over a distance of up to 100 m (328 feet).
z
Each Ethernet port on an S5100-50C-PWR-EI Ethernet switch provides a
maximum output power of 15.4 W for the connected devices. When AC power
input is used, the maximum output power for the whole system is 370 W; when DC
power input is used, the maximum output power for the whole system is 740 W.
V. Cooling system
An S5100-50C-PWR-EI Ethernet switch provides three fans for cooling the whole
device and three fans for cooling the power supply system.
1.4 LEDs
The S5100 series provide a power LED (PWR), a DC power LED (RPS), Gigabit
autosensing Ethernet port status LEDs, a Gigabit SFP port status LED, an Ethernet
port mode LED (MODE), module indicator, and a 7-segment digitron display.
1.4.1 Power LED (PWR)
The PWR LED is a green-red indicator.
