format of X.X and within the accuracy of the second decimal.
Description
Use the poe-power input-thresh lower command to set the undervoltage alarm
threshold of AC input for the PoE PSUs (lower threshold):
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.
Example
# Set the undervoltage alarm threshold of AC input to 181.0 V.
