Ac Input Alarm Threshold Configuration Example - H3C S7500 Series Operation Manual

Operation Manual – PoE
H3C S7500 Series Ethernet Switches
Enter the system view
Set the overvoltage
alarm threshold of AC
input (upper threshold)
for the PoE PSUs
Set the undervoltage
alarm threshold of AC
input (lower threshold)
for the PoE PSUs
Note:
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 264.0 V and the
lower threshold to 181.0 V.
For 110 VAC input, you are recommended to set the upper threshold to 132.0 V and
the lower threshold to 90.0 V.

2.2.2 AC Input Alarm Threshold Configuration Example

I. 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.
II. Configuration procedure
# Enter system view.
<H3C> system-view
# Set the overvoltage alarm threshold of AC input for PoE PSUs to 264.0 V.
[H3C] poe-power input-thresh upper 264.0
# Set the undervoltage alarm threshold of AC input for PoE PSUs to 181.0 V.
[H3C] poe-power input-thresh lower 181.0
# Display the AC input state of the PoE PSUs.
