Use Power-over-Ethernet (PoE) to eliminate using a 110/220 VAC power source to power access
points and other devices on a wired LAN. If using a Power-over-Ethernet system, only a single CAT5
Ethernet cable carrying both power and data to each device is required. The single cable scheme
provides greater flexibility in the placement of access points and network devices and can
significantly decrease installation costs.
Two configuration pages exist for the PoE function. The first allows per port configuration for specific
power restrictions on an individual port basis. The second configuration page is used for global
configurations that apply switch-wide.
Two functions are provided for the PoE control,
Port Configuration
Admin. status: The status of administration for a port.
Priority: Priority of a PoE port. Three selections are available, critical, high, and low.
When the power consumption over the power budget, the critical has higher
priority on power supplying.
Limit(mW): The maximum power supplied to a port. The default is 15.4W or 15000mW.
