The following table describes the basic critical and noncritical failures. This abbreviated list is representative; it is not intended as an exhaustive list. An error code is associated with each failure. Error codes appear on the Management Module Switch Information window. Be sure to note the applicable error code and corresponding failure. You might have to provide this information when you call the IBM HelpCenter®. For details, see Chapter 9, “Getting help and technical assistance,” on page 41.
