Concept Guide

When the system experiences a high temperature on any temperature sensor that exceeds the Critical threshold, a
shutdown log event is generated as show in the following examples:
Dell#Jun 18 01:57:03: %RPM1-P:CP %CHMGR-2-TEMP_SHUTDOWN_WARN: WARNING! linecard 11
temperature is 110C; approaching shutdown threshold of 110C)
Dell#Jun 18 01:57:04: %RPM1-P:CP %CHMGR-0-TEMP_SHUTDOWN_WARN: linecard 11 temperature
exceeded or equal to shutdown temperature 110C; Unit will shutdown now.Power cycle the
unit to power it on.
Example of Displaying Temperature threshold Values for Linecards and RPM

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.
