User's Manual

◦ Critical—Service lost or imminent service loss, immediate attention needed
◦ Disabled or Not installed—Service is unavailable or the component is not present.
◦ Unknown—A detected health problem cannot be classified
• Speed—The percentage of maximum speed at which the fan is currently running.
Viewing temperature information
The Temperatures page displays the status, current reading, threshold settings, and temperature
meter values for temperature sensors in the chassis.
For information about viewing cartridge and switch temperature readings, see “Viewing ProLiant
server cartridge information” (page 15) and “Viewing Moonshot switch information” (page 27).
The following temperature thresholds are monitored:
• Caution—The HP Moonshot System is designed to maintain a temperature below the caution
threshold.
If the temperature exceeds the Caution threshold, the fan speeds are increased to maximum.
If the temperature exceeds the Caution threshold for 60 seconds, a graceful shutdown of the
HP Moonshot system cartridges and switches is attempted.
• Critical—If temperatures are uncontrollable or rise quickly, the critical temperature threshold
prevents system failure by physically shutting down the HP Moonshot System cartridges and
switches before the high temperature causes an electronic component failure.
Monitoring policies differ depending on the chassis 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).
