Customer was observing temperature absolute high through NMS, when temperature goes above 70.
We did not see any logs with "temperature" in the messages. Hence our assumption was this is not system generated alarm, as we don't see same in device logs.
This must be a NMS generated alarm based on chassis environment temperature.
As per the temperature thresholds, 80 deg C is the minimum temperature where a log will be generated in device.
So customer need to check why NMS is generating alarm for whatever threshold they set there (may be change it to 80).
