Number Severity Description/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.
• A current sensor has been uninstalled.
Recommended actions:
• If a current sensor has exceeded the defined warning threshold values:
• 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, the indicated FRU has probably failed and should be replaced.
• If a current 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.
• 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.
