Configuring Voltage Alarm Thresholds and Masking
Undervoltage Alarms
Some hardware models include dual power interfaces for power redundancy. If you are only using one feed in a
dual-feed configuration, it is recommended to mask the unused feed in order to prevent an unnecessary
undervoltage alarm.
You can also configure undervoltage and overvoltage alarm thresholds. The default thresholds for PTP 820F, PTP
820G are:
•
Undervoltage Raise Threshold: 40V
•
Undervoltage Clear Threshold: 42V
•
Overvoltage Raise Threshold: 60V
•
Overvoltage Clear Threshold: 58V
These thresholds determine when the following alarms are raised and cleared:
•
Alarm #32000: Under voltage
•
Alarm #32001: Over voltage
To mask undervoltage alarms and configure voltage alarm thresholds:
1 Select Faults > Voltage Alarm Configuration . The Voltage Alarm Configuration page opens.
