You can enable and set them so that you are alerted when thetotal active energy or total active power hits a certain level.For a regular PX3TS model with multiple inlets: Total active energy = sum of all inlets' active energy values Total active power = sum of all inlets' active power valuesTo configure thresholds for total active energy and/or power:1. Click PDU. On the PDU page, you can also view the total active power andtotal active energy. SeePDU (on page 176).2. Click the Thresholds title bar at the bottom of the page to displaythresholds.
