| CFF module detected PSU fault | Fault | S11 |
| PSU removed | Configuration error | None2 |
| Enclosure configuration error (VPD) | Fault - critical | S11 |
| Low warning temperature alert | Warning | S11 |
| High warning temperature alert | Warning | S11 |
| Over temperature alarm | Fault - critical | S43 |
| I2C bus failure | Fault - loss of redundancy | S11 |
| Front panel communication error (I2C) | Critical fault | S11 |
| IOM module fault | Fault - critical | S11, 4 |

- 1 The enclosure will continue operating, requiring an administrator to take appropriate action; such as replacing a PSU or reducing the room temperature. Alarm messages will be in the COS System manager interface.
- 2 An alarm is not issued for this status and severity condition.
- 3 The enclosure will take action; such as shutting down in order to protect the enclosure’s data content. Alarm messages are signaled by the SES pages (see Enclosure management).
- 4 An IOM fault will prevent data from being stored within the Disk Enclosure.
