To display current temperature of line sensors, use the show environment thermal-sensors command. Minor threshold crossings
do not cause alarms, but are used to trigger increases in the speed of the system fans as needed to keep the component temperature
within the desired range.

To get the current sensor temperature of RPM, use the show rpm rpm-id.
In the following example, 29C is the CP card’s temperature in RPM. 52C is LP card’s sensor temperature in the RPM.

When a temperature threshold is crossed (either below or above the pre-congured value), the system logs an event that contains
information about the time when the event occurred, the type of event (minor, major, or shutdown), the current temperature of the sensor,
and the identity of the sensor. The system also logs events when the fan speeds change (increase or decrease) as a result of changes in
sensor temperature. To display the event log, use the show logging command.
The following examples display over-temperature event messages. Note that although the minimum speed for system fans is 40% of full
speed, the corresponding power-supply fan speed is 60% of full speed.
00:21:47: %SYSTEM:LP %CHMGR-2-FAN_SPEED_CHANGE: Fan speed changed to 40 % of the full speed
00:21:47: %SYSTEM:LP %CHMGR-2-PSU_FAN_SPEED_CHANGE: PSU_Fan speed changed to 60 % of the full
speed
00:27:35: %SYSTEM:LP %POLLMGR-2-SENSOR_TEMP_CHANGE: Switching Core Sensor S2, temperature 52C,
changed to Major state
