V. PoE
S5100-8P-PWR-EI Ethernet switches support Power Over Ethernet (PoE). They can
be connected to remote powered devices (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 power sourcing equipment (PSE), an S5100-8P-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 S5100-8P-PWR-EI Ethernet switch can provide power supplies through its
eight fixed Ethernet electrical ports over a distance of up to 100 m (328 feet).
z
Each Ethernet port on an S5100-8P-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 65 W.
VI. Cooling system
An S5100-8P-PWR-EI Ethernet switch provides two fans for heat dissipation.

I. Front panel
An S5100-16P-PWR-EI Ethernet switch provides 16 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 1-24 shows the front panel of an S5100-16P-PWR-EI
Ethernet switch.
