III. Side panel
An S5100-16P-PWR-EI Ethernet switch provides a lock hole for locking the switch to a
secure object for theft prevention.
The lock hole is on the back of the left side panel, as shown in Figure 1-3.
Note:
The lock hole cannot be used when the screw hole above it is in use.
IV. Power supply system
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
V. PoE
S5100-16P-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 S5100-16P-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 S5100-16P-PWR-EI Ethernet switch can provide power supplies through its 16
fixed Ethernet electrical ports over a distance of up to 100 m (328 feet).
z
Each Ethernet port on an S5100-16P-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 125 W.
