9.5 I/O Fault Descriptions and Corrective Actions
The I/O fault table reports the following data about faults:
▪ Fault Group
▪ Fault Action
▪ Fault category
▪ Fault type
▪ Fault description
All faults have a fault category, but a fault type and fault group may not be listed for every fault. To
view the detailed information pertaining to a fault, click the fault entry in the I/O Fault Table.
Note: The model number mismatch and I/O type mismatch faults are reported in the controller
fault table under the System Configuration Mismatch group. They are not reported in the I/O
fault table.
9.5.1 Fault Extra Data
An I/O fault table entry contains up to 21 bytes of I/O fault extra data that contains additional
information related to the fault. Not all entries contain I/O fault extra data.
