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
specified 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
specified system could not obtain a reading. The sensor location, chassis location,
previous state, and a nominal temperature sensor value information is provided.
