4.3. Fault Messages
A fault is a failure of a hardware component, a software component, or some
combination of components. A fault typically results in both an event and an alert. Refer
to
3.5.5 Event Log and 3.5.14 Alert Management for more information.
Some hardware components are customer-replaceable units (CRU), as discussed in
Section 11 Removing and Replacing CRUs and some are field-replaceable units (FRU).
If faults occur in CRUs or FRUs, the LED above the LCD turns amber and a message
appears on the fourth line of the main screen.
Figure 4-7 shows that faults occurred in
two FRUs in the named partition.
Note: The EXPRESSSCOPE® Monitor does not distinguish between CRUs and FRUs.
Instead, the term “FRU” appears on the LCD for both CRUs and FRUs.

Refer to the following paragraphs and Section 10 Troubleshooting Hardware Problems
for information on handling CRU and FRU faults.
