Temperature Sensor Messages
The temperature sensors listed help protect critical components by alerting the systems management console when temperatures become
too high inside a chassis. The temperature sensor messages use more variables: sensor location, chassis location, previous state, and
temperature sensor value or state.
Event ID — 1050
Description
Temperature sensor has failed Sensor location: <Location in chassis>
Chassis location: <Name of chassis>
Previous state was: <State>
If sensor type is not discrete:
Temperature sensor value (in degrees Celsius): <Reading>
If sensor type is discrete:
Discrete temperature state: <State>
Severity Error
Cause A temperature sensor on the backplane board, system board, or the carrier in the specied system failed. The
sensor location, chassis location, previous state, and temperature sensor value are provided.
Event ID — 1051
Description
Temperature sensor value unknown Sensor location: <Location in chassis>
Chassis location: <Name of chassis>
If sensor type is not discrete:
Temperature sensor value (in degrees Celsius): <Reading>
If sensor type is discrete:
Discrete temperature state: <State>
Severity Warning
Cause A temperature sensor on the backplane board, system board, or drive carrier in the specied system could not
obtain a reading. The sensor location, chassis location, previous state, and a nominal temperature sensor value
information is provided.
Event ID — 1052
Description
Temperature sensor returned to a normal value Sensor location: <Location in
chassis>
