Chapter 52 PoE PSU Supervision Configuration

52.1 Introduction to PoE PSU Supervision

The PoE-capable Switch 8800 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.

52.2 AC Input Alarm Thresholds Configuration

You can set the AC input alarm thresholds for the PoE PSUs to enable the Switch 8800
to monitor the AC input voltages of the PSUs in real time through the PoE supervision
module.
