Introduction to eXMP Temperature Monitoring
|
|
 IMPORTANT
WARNING! |
| |
The maximum environmental operating conditions
for the eXMP is 50 degrees C.
The maximum junction temperature of the eXMP processor is 90 degrees
C.
An eXMP shutdown will occur when the junction temperature reaches
135 degrees C. |

|
The eXMP protects itself from catastrophic overheating
by use of an internal thermal sensor. This sensor is set well above the
normal operating temperature to ensure that there are no false trips.
The processor will stop all execution when the junction temperature exceeds
approximately 135 degrees C. Precautions should be taken to monitor the
eXMP's junction temperature so that a controlled shutdown can be made
before an emergency shutdown occurs.
In the possible case of fan failure, the temperature
of the eXMP could rise to a point where the processor will generate an
unexpected emergency shutdown. The fan used in the eXMP has an MTBF of
30,000 hrs, depending on operating conditions.
To protect eXMP users from an unexpected shutdown, we
have added a Temperature Monitoring Feature into the MPI. Please see Using
the MPI to Check the Temperature for more information.
