Table 27. Event descriptions and recommended actions (continued)
Number Severity Description/Recommended actions
Recommended actions:
● If temperature sensor is outside critical temperature threshold in the indicated FRU.
○ Check that the ambient temperature is not too warm. For the normal operating range,
see your product's Hardware Installation and Maintenance Guide.
○ Check for any obstructions to the airflow.
○ Check that all modules in the enclosure are fully seated in their slots and that their
latches, if any, are locked.
○ Check that all fans in the enclosure are running.
○ Check that there is a module or blank plate in every module slot in the enclosure.
○ If none of these recommended actions resolve the issue, the indicated FRU has probably
failed and should be replaced.
● The temperature sensor is not able to communicate with the EMP.
○ Wait for at least 10 minutes and check if the error resolves.
○ If the error persists, check that all modules in the enclosure are fully seated in their slots
and that their latches, if any, are locked.
○ If this does not resolve the issue, note down the FRU. Ensure the partner FRU is not
degraded. If the partner FRU is degraded, contact technical support.
○ For all FRU types except the enclosure, if the partner FRU is not degraded, remove and
reinsert the indicated FRU.
○ If the indicated FRU is the enclosure, set up a preventive maintenance window and power
cycle the enclosure at that time.
○ If these recommended actions do not resolve the issue, the indicated FRU has probably
failed and should be replaced.
When the problem is resolved, an event with the same code will be logged with Resolved
severity.
Warning
A temperature sensor is not within normal operating temperature thresholds but is within safe
operating limits; or, a temperature sensor has been uninstalled.
Recommended actions:
● If a temperature sensor has exceeded the normal operating range but is within safe operating
limits.
○ Check that the ambient temperature is not too warm. For the normal operating range,
see your product's Hardware Installation and Maintenance Guide.
○ Check for any obstructions to the airflow.
● If a temperature sensor has been uninstalled:
○ Check that the indicated FRU is in the indicated enclosure.
● If the FRU is not in the enclosure, install the FRU immediately.
● If the FRU is in the enclosure, ensure that the FRU is fully seated in its slot and that its
latches, if any, are locked.
When the problem is resolved, an event with the same code will be logged with Resolved
severity.
Resolved A SES alert for a temperature sensor in the indicated enclosure has been resolved.
Recommended actions:
● No action is required.
554 Error A voltage sensor reported an alert condition.
● A voltage sensor is outside a critical voltage threshold in the indicated FRU.
● A voltage sensor is not able to communicate with the EMP.
Recommended actions:
● If a voltage sensor is outside a critical voltage threshold in the indicated FRU:
○ Check that all modules in the enclosure are fully seated in their slots and that their
latches, if any, are locked.
