Yes. Many POE installations connecting the switches / mid-span injectors to UPSs. This will enable all Jack-PC thin-clients to operate from a UPS in case of a power failure just like IP phones.
You have 2 options:
a. Use Power Over Ethernet mid-span injector to inject power to that port (or to many ports if multiple ports injector used).
b. Use POE switch to power that port. These products becoming very standard now due to IP telephony and the cost added per port is small.
What are the advantages of powering the Jack-PC with POE?
Several advantages:
a. Independency on local power source
b. Simpler deployment (installation)
c. Higher reliability, less wires and failure points
d. Easier UPS powering
e. Better control (through managed and monitored POE source)
f. Safety
g. Standardization with other desktop appliances such as IP phones
h. Higher security (enabling locked, always on device)
i. Less vulnerability to power induced disasters such as lightning strikes and static electricity
j. Global standardization (no need to maintain different SKUs for different power options).
k. Less shipping weight and size
l. Higher efficiency - less power consumption and heat
No. There is no effect on the network operation or performance. As any NIC has a transformer in the network front end to isolate it electrically form the LAN cable, this transformer does not allow the LAN transceiver to sense the power on the cable. Data doesn't know about the power!
Can I control the power supplied to a specific POE port?
Yes. Many of the new POE switches and mid-span injectors provides GUI to control the POE setting of each port and to monitor its condition. Typical GUI can show if device is connected and powered, its actual power consumption (current in Amps). It usually provide port POE enable / disable and setting of POE Class (power consumption range). For Jack-PC always enable maximum power (Class E).
What happens if Jack-PC takes too much power from POE?
Not a big chance that you will do it unless you found good way to over load all USB ports. In such case the over-current protection in the client side (Jack-PC) or in the power source will cut the power to the device.
