poe-power input-thresh lower string

System view

string: Undervoltage alarm threshold. It ranges from 90.00 V to 264.00 V in the 
format of X.X and within the accuracy of the second decimal.

Use the poe-power input-thresh lower command to set the undervoltage alarm 
threshold of AC input for the PoE PSUs (lower threshold):

■

For 220 VAC input, it is recommended to set the threshold to 181.0 V.

■

For 110 VAC input, it is recommended to set the threshold to 90.0 V.

# Set the undervoltage alarm threshold of AC input to 181.0 V.

[SW8800] poe-power input-thresh lower 181.0

 

Set lower input-threshold power successfully! 

poe-power input-thresh upper string

System view

string: Overvoltage alarm threshold. It ranges from 90 V to 264 V in the format of 
X.X.

Use the poe-power input-thresh upper command to set overvoltage alarm 
threshold of AC input (upper threshold):

■

For 220 VAC input, it is recommended to set the threshold to 264.0 V.

■

For 110 VAC input, it is recommended to set the threshold to 132.0 V.

# Set the overvoltage alarm threshold of AC input to 264.0 V.

[SW8800] poe-power input upper 264.0

 

Set upper input-threshold power successfully!
