H3C S9500 Series Routing Switches
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 V and the
lower threshold to 181 V.
For 110 VAC input, it is recommended to set the upper threshold to 132 V and the
lower threshold to 90 V.
2.2.2 Configuring DC Output Alarm Thresholds
You can set the DC output alarm thresholds for the PoE PSUs to enable the S9500
series to monitor the DC output voltages of the PSUs in real time through the PoE
supervision module.
Follow these steps to configure DC output alarm thresholds:
Enter system view
Set the overvoltage alarm
threshold of DC output
(upper threshold) for the
PoE PSUs
Set the undervoltage
alarm threshold of DC
output (lower threshold)
for the PoE PSUs
Display the DC output
state of the PoE PSUs.
Display the DC output
voltage/current value of
the PoE PSUs
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.
