be shut down. Based on the industry standard, 802.3af, there are 4 kinds of PD classes, class 
0, class 1, class 2, and class 3. The power consumption ranges for them are 0.44~12.95W, 
0.44~3.84W, 3.84~6.49W, and 6.49~12.95W respectively. The four pre-defined settings are 
for the users’ convenience: The following is the power limit applied to the port for these four 
classes. For each class, the power limit is a little more than the power consumption range for 
the class. This takes the factor of the power loss on cable into account. 
class_0 - Specifies that the power limit will be set to 15400mW. 
class_1 - Specifies that the power limit will be set to 4000mW. 
class_2 - Specifies that the power limit will be set to 7000mW. 
class_3 - Specifies that the power limit will be set to 15400mW. 
user_define - Specifies the user defined power limit value here. 
<value 1000-35000> - Enter the user defined port limit value used here. This value must 
be between 1000 and 35000mW. Other than the four pre-defined settings, the users 
can directly specify any value that the chip supports. Normally, the minimum setting is 
1000mW, and the maximum setting is 15400mW for 802.3af and greater or equal to
