ONFIGURATION
The PoE-capable Switch 8800 Family series can monitor the external PoE PSUs
through the power supervision module on the PoE external power system.
The PoE PSU supervision module enables you to:
Set the alarm thresholds for the AC input voltages of the PoE PSUs.
■
Set the alarm thresholds for the DC output voltages of the PoE PSUs.
■
Query PSU information such as voltage and power.
■
You can set the AC input alarm thresholds for the PoE PSUs to enable the Switch
8800 Family series to monitor the AC input voltages of the PSUs in real time
through the PoE supervision module.

You can set the thresholds to any appropriate values in the range, but make
■
sure the lower threshold is less than the upper threshold.
For 220 VAC input, it is recommended to set the upper threshold to 264 V and
■
the lower threshold to 181 V.
For 110 VAC input, it is recommended to set the upper threshold to 132 V and
■
the lower threshold to 90 V.
Network requirements
Set the overvoltage alarm threshold of AC input for PoE PSUs to 264.0 V.
■
Set the undervoltage alarm threshold of AC input for PoE PSUs to 181.0 V.
