5. If the selected sensor is a numeric sensor, its threshold settings are
displayed in the dialog. See
Sensor Threshold Settings
(on page
529) for detailed information.
There are two types of thresholds: sensor-specific thresholds and
default thresholds.
To use the sensor-specific threshold settings, select the Use Sensor
Specific Thresholds radio button.

Click Edit or double-click the threshold setting row to open the
threshold setup dialog.
 To enable any threshold, select the corresponding checkbox. To
disable a threshold, deselect the checkbox.
 After any threshold is enabled, type an appropriate numeric value
in the accompanying text box.
 To set the deassertion hysteresis, type a numeric value in the
Deassertion Hysteresis field. See
"To De-assert" and
Deassertion Hysteresis
(on page 534).
 To set the assertion timeout, type a numeric value in the
Assertion Timeout (samples) field. See
"To Assert" and
Assertion Timeout
(on page 532).
To use the default threshold settings, select the Use Default
Thresholds radio button. To modify the default threshold settings, see
Changing Default Thresholds
(on page 249).
Note: The Upper Critical and Lower Critical values are points at
which the EMX considers the operating environment critical and
outside the range of the acceptable threshold.
6. Click OK.
7. Repeat the same steps to configure additional ones.
Tip: You can configure thresholds of multiple sensors at a time as long
as these sensors belong to the same type. See
Setting Thresholds for
Multiple Sensors (on page 250).
Setting the Z Coordinate Format
You can use either the number of rack units or a descriptive text to
describe the vertical locations (Z coordinates) of environmental sensors
and actuators.
To determine the Z coordinate format:
1. In the left pane, click the EMX folder. The Settings page opens.
Note: This folder's name changes after customizing the device name.
See
Naming the EMX (on page 110).
