● If this event is logged more than one time as Warning severity, do the following:

○ 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.
