DC Output Alarm 
Thresholds 
Configuration
You can set the DC output alarm thresholds for the PoE PSUs to enable the Switch 
8800 Family series to monitor the DC output voltages of the PSUs in real time 
through the PoE supervision module.

Configuration Tasks
For both 220 VAC and 110 VAC input, it is recommended to set the upper 
threshold to 57.0 V and the lower threshold to 45.0 V.
