The Class field in Figure 4 refers to the IEEE 802.3af Power Classification system (Table 2).
The FS726TP measures power at the FS726TP. The Power Limit column in Figure 4 refers to
the IEEE 802.3af Maximum Power at the power source.
Class
Maximum
Power at
FS726TP
0 15.4W
1 4.0W
2 7.0W
3 15.4W
Table 2: IEEE 802.3 Power Classifications
If all of the devices are Class 2 or lower, there will be no need to assign Priority because the
total power will not exceed the Max System Power Available. If more than one of the devices
is Class 0 or Class 3, select a Priority for each port to control which ports will be shut down in
the event the powered devices exceed the Max System Power Available. In situations where a
large number of Class 0 or Class 3 devices are used, Medium priority should be assigned to one
group of the Class 0/3 devices and Low to a second group.
Figure 6: NETGEAR FS726TP PoE Priority
Assign enough Low Priority ports so that if the Max System Power Available is exceeded, the
high priority devices in the enterprise will be powered.
