NOTE: You can track the temperature history even for systems that are not fresh air compliant. However, the threshold
limits and fresh air related warnings generated are based on fresh air supported limits. The limits are 42ºC for warning
and 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). The
system 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). The
system 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 cleared
only before shipping from the factory.
An event is generated if the system continues to operate above the normally supported temperature threshold for a specified
operational 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. The
events 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
Viewing historical temperature data using iDRAC web interface
To 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 RACADM
To 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 temperature
You can modify the minimum and maximum warning threshold values for the system board inlet temperature sensor. If reset to
default action is performed, the temperature thresholds are set to the default values. You must have Configure user privilege to set
the warning threshold values for the inlet temperature sensor.
Configuring warning threshold for inlet temperature using web interface
To 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 the
Warning Threshold in Centigrade or Fahrenheit. If you enter the value in centigrade, the system automatically calculates and
displays the Fahrenheit value. Similarly, if you enter Fahrenheit, the value for Centigrade is displayed.
