Setting a Circuit Breaker's Thresholds
Setting the circuit breaker thresholds enables the PDU to generate alerts
when any circuit breaker crosses the thresholds.
To set the thresholds for a circuit breaker:
1. Expand the Overcurrent Protectors folder to show all circuit breakers
in the Dominion PX Explorer pane. See
Expanding the Tree
(on page
71).
Note: The PDU folder is named "my PX" by default. The name
changes after customizing the device name. See
Naming the PDU
(on page 83).
2. Click the desired circuit breaker in the Dominion PX Explorer pane,
and the page for this circuit breaker opens in the right pane.
3. Click
Setup.
The
Overcurrent Protector Setup dialog appears.
4. In the Threshold Configuration table, click the sensor whose
thresholds you want to configure.
5. Click Edit. A threshold setup dialog for the selected sensor appears.
Tip: You can also double-click the desired sensor in the Threshold
Configuration table to trigger this dialog.
6. Configure the Lower Critical, Lower Warning, Upper Warning and
Upper Critical thresholds respectively.
To enable any threshold, select the corresponding checkbox. To
disable a threshold, deselect the checkbox.
