Troubleshoot an Over-Temperature Condition To troubleshoot an over-temperature condition, determine the sensor(s) that triggered the over-temperature alarm by displaying the current temperature levels and the historical logs of the temperature threshold-crossing events. The RPM has CP and LP card whose sensor temperature are monitored. Similarly the Linecard's sensor is monitored as well. The "show alarm threshold" provides the temperature threshold values for Linecards and RPM. The Threshold values of linecard applies to linecards 0 - 9 as well as the LP card residing in RPM. The threshold value of RPM applies to the CP card. Under minor temperature alarm condition in any of the components (Linecard or RPM), the Fan speed is increased from 70% to 80%. Under major temperature alarm condition in any of the components (Linecard or RPM), the Fan speed is increased from 90% to 100%. The following example syslogs zfdtemperature alarm condition in the system. Jun 18 01:49:03: %RPM1-P:CP %CHMGR-2-MINOR_TEMP: Minor alarm: chassis temperature (linecard 0 temperature reaches or exceeds minor threshold of 99C) Jun 18 01:54:30: %RPM1-P:CP %CHMGR-2-MAJOR_TEMP: Major alarm: chassis temperature high (RPM 1 temperature reaches or exceeds threshold of 48C) Jun 18 01:55:22: %RPM1-P:CP %CHMGR-2-MAJOR_TEMP: Major alarm: chassis temperature high (linecard 11 temperature reaches or exceeds threshold of 105C) Examples of Syslog Temperature Alarm Conditions The following are example syslogs temperature alarm conditions in the system. Jun 18 01:49:03: %RPM1-P:CP %CHMGR-2-MINOR_TEMP: Minor alarm: chassis temperature (linecard 0 temperature reaches or exceeds minor threshold of 99C) Jun 18 01:54:30: %RPM1-P:CP %CHMGR-2-MAJOR_TEMP: Major alarm: chassis temperature high (RPM 1 temperature reaches or exceeds threshold of 48C) Jun 18 01:55:22: %RPM1-P:CP %CHMGR-2-MAJOR_TEMP: Major alarm: chassis temperature high (linecard 11 temperature reaches or exceeds threshold of 105C) Examples of Syslog with a Critical Temperature Threshold Event 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.
