<hy_value> is the deassertion hysteresis value applied to the specified sensor type.
<as_value> is the assertion timeout value applied to the specified sensor type. It ranges from 0 to 100
(samples).
Example - Default Upper Thresholds for Temperature
It is assumed that your preferred measurement unit for temperature is set to degrees Celsius. Then the
following command sets the default Upper Warning threshold to 20
and Upper Critical threshold to 24
for all temperature sensors.
config:# defaultThresholds temperature upperWarning 20
upperCritical 24
Sensor Threshold Configuration Commands
A sensor configuration command begins with sensor. You can use the commands to configure the threshold,
hysteresis and assertion timeout values for any sensor associated with the following items:
Inlets
Inlet poles (for three-phase PDUs only)
Overcurrent protectors
Environmental sensors
It is permitted to assign a new value to the threshold at any time regardless of whether the threshold has
been enabled.
Commands for Inlet Sensors
A sensor configuration command for inlets begins with sensor inlet.
You can configure various inlet sensor threshold settings at a time by combining multiple commands. See
Multi-Command Syntax (on page 381).
Set the Upper
Critical threshold for an inlet sensor:
config:# sensor inlet <n> <sensor type> upperCritical <option>
Set the Upper Warning threshold for an inlet sensor:
