2.1 Introduction to PoE PSU Supervision
The PoE-enabled S7500 series can monitor the external PoE power supply units
(PSUs) through SRPUs.
Complete these tasks to configure PoE PSU supervision:
Task Remarks
AC Input Alarm Thresholds Configuration Required
DC Output Alarm Threshold Configuration Required
 Note:
The PSE performance will be affected by fast switching of PoE PSUs. The interval of
switching PoE PSUs must be greater than five seconds.
2.2 AC Input Alarm Thresholds Configuration
You can set the AC input alarm thresholds for the PoE PSUs to enable the S7500
series to monitor the AC input voltages of the PSUs in real time through SRPUs.
2.2.1 Configuring AC Input Alarm Threshold
Follow these steps to configure AC input alarm thresholds:
