2.3 DC Output Alarm Threshold Configuration
You can set the DC output alarm thresholds for the PoE PSUs to enable the S7500
series to monitor the DC output voltages of the PSUs in real time through SRPUs.
2.3.1 DC Output Alarm Thresholds Configuration Tasks
Follow these steps to set DC output alarm thresholds:
To do… Use the command… Remarks
Enter the system view
system-view
—
Set the overvoltage alarm
threshold of DC output
(upper threshold) for the
PoE PSUs
poe-power
output-thresh upper
string
Required
You are recommended to
set the upper threshold to
47 V when 220 VAC or
110 VAC is input.
Set the undervoltage
alarm threshold of DC
output (lower threshold)
for the PoE PSUs
poe-power
output-thresh lower
string
Required
You are recommended to
set the lower threshold to
55 V when 220 VAC or
110 VAC is input.
2.3.2 DC Output Alarm Threshold Configuration Example
I. Network requirements
z Set the overvoltage alarm threshold of DC output for the PoE PSUs to 55.0 V.
z Set the undervoltage alarm threshold of DC output for the PoE PSUs to 47.0 V.
II. Configuration procedure
# Enter system view.
