Parameters
slot slot-number: See Table 22.
hotspot: Specifies a hotspot sensor, which is used for temperature monitoring and is typically placed
near the chip that generates a great amount.
sensor-number: Specifies the sensor number. It is an integer starting from 1, each number representing a
temperature sensor of a device or card.
lowerlimit: Lower temperature threshold in Celsius degrees. The value range depends on the hotspot
sensor.
warninglimit: Warning temperature threshold in Celsius degrees. The value range depends on the
hotspot sensor.
alarmlimit: Alarming temperature threshold in Celsius degrees. The value range depends on the hotspot
sensor. The value of this argument must be greater than the warning temperature threshold. If you do not
specify this argument, the current configuration is used.
Usage guidelines
When the device temperature drops below the lower temperature threshold or reaches the warning
threshold, the device logs the event and outputs a log message and a trap.
When the device temperature reaches the alarming threshold, the device logs the event and outputs a log
message and a trap repeatedly, and alerts users through the LED on the device panel.
Due to temperature hysteresis, a temperature decreasing notification is later than the actual temperature
decreasing event. Fan speed changes might cause the actual temperature value read after an alarm to
be lower than the alarm temperature.
