Operation Manual – PoEH3C S9500 Series Routing Switches Chapter 2 PoE PSU Supervision Configuration2-2Note:z You can set the thresholds to any appropriate values in the range, but make surethe lower threshold is less than the upper threshold.z For 220 VAC input, it is recommended to set the upper threshold to 264 V and thelower threshold to 181 V.z For 110 VAC input, it is recommended to set the upper threshold to 132 V and thelower threshold to 90 V.2.2.2 AC Input Alarm Thresholds Configuration ExampleI. Network requirementsz Set the overvoltage alarm threshold of AC input for PoE PSUs to 264.0 V.z Set the undervoltage alarm threshold of AC input for PoE PSUs to 181.0 V.II.
