Note:
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.

2.3.2 DC Output Alarm Thresholds Configuration Example

I. Network requirements
Set the overvoltage alarm threshold of DC output for the PoE PSUs to 57.0 V.
Set the undervoltage alarm threshold of DC output for the PoE PSUs to 45.0 V.
II. Configuration procedure
# Enter system view.
<H3C> system-view
# Set the overvoltage alarm threshold of DC output for the PoE PSUs to 57.0 V.
[H3C] poe-power output-thresh upper 57.0
# Set the undervoltage alarm threshold of DC output for the PoE PSUs to 45.0 V.
[H3C] poe-power output-thresh lower 45.0
# Display the DC output state of the PoE PSUs.
[H3C] display poe-power dc-output state
# Display the DC output voltage/current values of the PoE PSUs.
[H3C] display poe-power dc-output value

2.4 Displaying PoE Supervision Information

After completing the above configurations, you can execute the display command in
any view to query the PoE state of the switch. Then you can view the display output to
check the effect of these configurations.
