•
If this event is logged more than one time as Warning severity, do the following:
– Check the version of the controller firmware and update to the latest firmware if needed.
– If the latest firmware is already installed, the controller module that logged this event probably has a
hardware fault. Replace the module.

If you are
not
able to access the management interfaces of the controller that logged this event, do the
following:
– Shut down that controller and reseat the module.
– If you are then able to access the management interfaces, check the version of the controller firmware
and update to the latest firmware if needed.
– If the problem recurs, replace the module.
