NOTE: You can track the temperature history even for systems that are not fresh air compliant. However, the thresholdlimits and fresh air related warnings generated are based on fresh air supported limits. The limits are 42ºC for warningand 47ºC for critical. These values correspond to 40ºC and 45ºC fresh air limits with 2ºC margin for accuracy.Two fixed temperature bands are tracked that are associated to fresh air limits:• Warning band — Consists of the duration a system has operated above the temperature sensor warning threshold (42ºC). Thesystem can operate in the warning band for 10% of the time for 12 months.• Critical band — Consists of the duration a system has operated above the temperature sensor critical threshold (47ºC). Thesystem can operate in the critical band for 1% of the time for 12 months which also increments time in the warning band.The collected data is represented in a graphical format to track the 10% and 1% levels. The logged temperature data can be clearedonly before shipping from the factory.An event is generated if the system continues to operate above the normally supported temperature threshold for a specifiedoperational time. If the average temperature over the specified operational time is greater than or equal to the warning level (> =8%) or the critical level (> = 0.8%), an event is logged in the Lifecycle Log and the corresponding SNMP trap is generated. Theevents are:• Warning event when the temperature was greater than the warning threshold for duration of 8% or more in the last 12 months.• Critical event when the temperature was greater than the warning threshold for duration of 10% or more in the last 12 months.• Warning event when the temperature was greater than the critical threshold for duration of 0.8% or more in the last 12 months.• Critical event when the temperature was greater than the critical threshold for duration of 1% or more in the last 12 months.You can also configure iDRAC to generate additional events. For more information, see the Setting alert recurrence event section.Viewing historical temperature data using iDRAC web interfaceTo view historical temperature data:1. In the iDRAC Web interface, go to Overview → Server → Power / Thermal → Temperatures.The Temperatures page is displayed.2. See the System Board Temperature Historical Data section that provides a graphical display of the stored temperature(average and peak values) for the last day, last 30 days, and last year.For more information, see the iDRAC Online Help.NOTE: After an iDRAC firmware update or iDRAC reset, some temperature data may not be displayed in the graph.Viewing historical temperature data using RACADMTo view historical data using RACADM, use the inlettemphistory command.For more information, see the iDRAC RACADM Command Line Reference Guide available at dell.com/idracmanuals.Configuring warning threshold for inlet temperatureYou can modify the minimum and maximum warning threshold values for the system board inlet temperature sensor. If reset todefault action is performed, the temperature thresholds are set to the default values. You must have Configure user privilege to setthe warning threshold values for the inlet temperature sensor.Configuring warning threshold for inlet temperature using web interfaceTo configure warning threshold for inlet temperature:1. In the iDRAC Web interface, go to Overview → Server → Power/Thermal → Temperatures.The Temperatures page is displayed.2. In the Temperature Probes section, for the System Board Inlet Temp, enter the minimum and maximum values for theWarning Threshold in Centigrade or Fahrenheit. If you enter the value in centigrade, the system automatically calculates anddisplays the Fahrenheit value. Similarly, if you enter Fahrenheit, the value for Centigrade is displayed.105
