Viewing temperature information

The Temperature Information page displays the location, status, temperature, and threshold settings
of temperature sensors in the server chassis.

If the server is powered off, the system health information on this page is current as of the last
power off. Health information is updated only when the server is powered on and POST is complete.

The temperature is monitored to maintain the sensor location temperature below the caution
threshold. If one or more sensors exceed this threshold, iLO implements a recovery policy to prevent
damage to server components.

If the temperature exceeds the caution threshold, the fan speed is increased to maximum.

If the temperature exceeds the caution threshold for 60 seconds, a graceful server shutdown
is attempted.

If the temperature exceeds the critical threshold, the server is shut down immediately to prevent
permanent damage.

Monitoring policies differ depending on the server requirements. Policies usually include increasing
fan speeds to maximum cooling, logging temperature events in the IML, providing a visual indication
of events by using LED indicators, and starting a graceful shutdown of the operating system to
avoid data corruption.

Additional policies are implemented after an excessive temperature condition is corrected, including
returning the fan speed to normal, recording the event in the IML, turning off the LED indicators,
and canceling shutdowns in progress (if applicable).

Viewing temperature sensor data

To view temperature sensor data, navigate to the Information

→System Information page, and then

click the Temperatures tab, as shown in

.

When temperatures are displayed in Celsius, click the Show values in Fahrenheit button to change
the display to Fahrenheit. When temperatures are displayed in Fahrenheit, click the Show values
in Celsius button to change the display to Celsius.
