To recognize thiscondition, look for the system messages in Message 7.To view the programmed alarm thresholds levels, including the shutdown value, execute the show alarmsthreshold command shown in Figure 60-6.Figure 60-6. show alarms threshold Command ExampleTroubleshoot an overtemperature conditionTo troubleshoot an over-temperature condition:1.
