S5100-50C-Pwr-Ei Ethernet Switch - H3C S5100-SI Series Installation Manual

Installation Manual
H3C S5100-SI/EI Series Ethernet Switches
III. Power supply system
An S5100-26C-PWR-EI switch provides AC power input and RPS DC input. The
AC/DC power inputs can be used at the same time, acting as backup for each other.
Alternatively, you can use either the AC power input alone or the DC power input alone.
Make sure you use an RPS module recommended by H3C as the DC power input.
AC input:
Rated voltage range: 100 VAC to 240 VAC; 50 Hz or 60 Hz
Max voltage range: 90 VAC to 264 VAC; 47 Hz to 63 Hz
DC input:
Voltage range: -52 VDC to -55 VDC
IV. PoE
S5100-26C-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.
When serving as a PSE, an S5100-26C-PWR-EI Ethernet switch supports
IEEE802.3af standards and can also supply power to some of the PDs
incompatible with 802.3af standards.
An S5100-26C-PWR-EI Ethernet switch can provide power supplies through its 24
fixed Ethernet electrical ports over a distance of up to 100 m (328 feet).
Each Ethernet port on an S5100-26C-PWR-EI Ethernet switch provides a
maximum output power of 15.4 W for the connected devices. The maximum
output power for the whole system is 370 W.
V. Cooling system
An S5100-26C-PWR-EI Ethernet switch provides two fans for cooling the whole device
and three fans for cooling the power supply system.

I. Front panel
An S5100-50C-PWR-EI Ethernet switch provides 48 x 10/100/1000Base-T
autosensing Ethernet ports, four 1000Base-X SFP ports, and one console port on the
front panel. An SFP port and its corresponding 10/100/1000Base-T autosensing
Ethernet port form a Combo port. That is, only one of the two ports forming the Combo
port can be used at a time. Table 1-2 shows the mapping relations between the ports
forming the Combo port. Figure 1-28 shows the front panel of an S5100-50C-PWR-EI
Ethernet switch.
