PoE port power allocation

The 8348TX-PWR and 8348GTX-PWR modules support a maximum of 800 watts PoE power
for each module. The 8348TX-PWR and 8348GTX-PWR modules support an average of 4
watts over all 48 ports, or 12 ports operating at 15.4 watts, or any combination of these,
provided the total power does not exceed 200 watts at the default power allocation settings.
The Ethernet Routing Switch 8300 configures a maximum of 15.4 watts of PoE power limit for
each port by default. Use the software to configure power allocation in 1-watt units.
The Ethernet Routing Switch 8300 provides up to 15.4 watts for each port by default. When
classification is supported and enabled, the port power allocation is determined by the
classification detection result.
The following table lists the maximum power level for powered devices.
