Temperature graph details
When you view the temperature graph, the circles on the graph correspond to the sensors listed in the
Sensor Data table.
The color on the graph is a gradient that ranges from green to red. Green represents a temperature of
0°C and red represents the critical threshold. As the temperature of a sensor increases, the graph color
changes from green to amber, and then to red if the temperature approaches the critical threshold.
Viewing temperature sensor data
Procedure
1. Click Power & Thermal in the navigation tree, and then click the Temperatures tab.
2. Optional: When temperatures are displayed in Celsius, click the Show values in Fahrenheit switch to
change the display to Fahrenheit. When temperatures are displayed in Fahrenheit, click the Show
values in Celsius switch to change the display to Celsius.
3. Optional: By default, sensors that are not installed are hidden. To view the missing sensors, click
show missing sensors. When missing sensors are displayed, click hide missing sensors to hide
them.
Temperature sensor details
• Sensor—The ID of the temperature sensor, which also gives an indication of the sensor location.
• Location—The area where the temperature is being measured. In this column, Memory refers to the
following:
â—¦ Temperature sensors on physical memory DIMMs.
â—¦ Temperature sensors located close to the memory DIMMs, but not on the DIMMs. These sensors
are located further down the airflow cooling path, near the DIMMs, to provide additional
temperature information.
The ID of the temperature sensor in the Sensor column helps to pinpoint the location, providing
detailed information about the DIMM or memory area.
• X—The x-coordinate of the temperature sensor.
• Y—The y-coordinate of the temperature sensor.
• Status—The temperature status.
• Reading—The temperature recorded by the temperature sensor. If a temperature sensor is not
installed, the Reading column shows the value N/A.
• Thresholds—The temperature thresholds for the warning for overheating conditions. The two
threshold values are Caution and Critical. If a temperature sensor is not installed, the Thresholds
column shows the value N/A.
Temperature monitoring
The following temperature thresholds are monitored:
• Caution—The server is designed to maintain a temperature lower than the caution threshold.
If the temperature exceeds the caution threshold, the fan speeds are increased to maximum.
