Power over Ethernet
Power over Ethernet (PoE) provides a way to distribute low-voltage power
across the network using existing Ethernet cable to a powered device
(PD). This allows the devices to operate without power adapters or AC
outlets. Powered devices include IP telephones, wireless LAN access
points, and surveillance cameras. Of the 24 ports on the AT-FS750/
24POE Fast Ethernet Smart Switch Switch, 12 are PoE-capable.
This chapter contains the following sections:
“PoE Overview” on page 34
“Viewing the PoE Status” on page 36
“Setting the Power Management Mode” on page 38
