INTELLIGENT PDU USER MANUAL
The Reset threshold is the number of watts the reading needs to fall below
the threshold setting for the condition to be cleared.
For example, the current critical threshold for the input phase is set to 19
watts (W). The current draw rises to 20W, triggering a Current Critical alert.
The current then continues to fluctuate between 18.1W and 20W. With the
reset threshold set to 1W, the PDU continues to indicate that the current on
the input phase is above critical. Without a reset threshold (that is, the reset
threshold is set to zero), the PDU would de-assert the condition each time the
current dropped to 18.9W and re-assert the condition each time the current
reached 19W or higher. With the fluctuating current, this could result in
repeating event notifications, such as SNMP traps, SMTP alerts or Syslog
notifications.
• Alarm State Change Delay (samples)
If enabled, the PDU asserts any warning or critical condition only after a
specified number of consecutive samples that cross a threshold are
generated. This prevents several threshold alerts from being generated if the
measurements return to normal immediately after rising above an upper
threshold or dropping below a lower threshold.
4. Repeat steps 1 - 3 for all PDUs.
Energy Threshold
The PANDUIT PDU will send alert notifications when an energy threshold kilowattage
crosses above or below the settings you specify in the Energy Threshold configuration:
1. Go to the Thresholds > Energy Page.
2. Click the pencil for the Energy Threshold to update.
