Table 27. Event descriptions and recommended actions (continued)
Number Severity Description/Recommended actions
● Replace the module that contains the indicated expander. This could be an IOM, sideplane or
a drawer. Contact technical support for replacement of the module containing the drawer
expander.
CAUTION: The sideplanes on the enclosure drawers are not hot swappable or
customer serviceable.
● If these recommended actions do not resolve the issue, contact technical support. The
enclosure must be replaced.
When the problem is resolved, an event with the same code will be logged with Resolved
severity.
Warning An alert condition was detected on a root expander or drawer expander element.
Recommended actions:
● If uninstalled, the expander associated with the sideplane or drawer will have to be installed.
Contact technical support. Otherwise, replace the module that contains the indicated
expander. This could be a sideplane or a drawer. Contact technical support for replacement
of the module containing the drawer expander.
CAUTION: The sideplanes on the enclosure drawers are not hot swappable or
customer serviceable.
● If these recommended actions do not resolve the issue, contact technical support. The
enclosure must be replaced.
When the problem is resolved, an event with the same code will be logged with Resolved
severity.
Resolved A SES alert for an expander in the indicated enclosure has been resolved.
Recommended actions:
● No action is required.
557 Error An Enclosure Management Processor (EMP) reported an alert condition on a current sensor.
● The EMP is unable to communicate with the indicated current sensor.
● The current sensor is outside critical threshold values.
Recommended actions:
● If the EMP is unable to communicate with the indicated current sensor:
○ 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, 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.
● If the current sensor is outside critical threshold values:
○ Check that all modules in the enclosure are fully seated in their slots and that their
latches, if any, are locked.
○ 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
An Enclosure Management Processor (EMP) reported an alert condition on a current sensor.
● A current sensor is outside the defined warning threshold values.
