Diagnostic Steps
This section describes possible reasons and actions to take when an LED indicates a fault
condition during initial system setup. See
Appendix A
for descriptions of all LED statuses.
NOTE :
Once event notification is configured and enabled using RAIDar, you can
view event logs to monitor the health of the system and its components
using the GUI.
In addition to monitoring the LEDs via line-of-sight observation of the racked hardware
components when performing diagnostic steps, you can also monitor the health of the
system and its components using the management interfaces previously discussed. Bear this
in mind when reviewing the
Actions
column in the following diagnostics tables, and when
reviewing the step procedures provided later in this chapter.

Actions
No

No action required.
Yes
A fault condition exists/occurred.
If installing an I/O module FRU, the
module has gone online and likely failed
its self-test.
• Check the LEDs on the back of the controller to
narrow the fault to a FRU, connection, or both.
• Check the event log for specific information
regarding the fault; follow any Recommended
Actions.
• If installing an IOM FRU, try removing and
reinstalling the new IOM, and check the event
log for errors.
• If the above actions do not resolve the fault,
isolate the fault, and contact an authorized
service provider for assistance. Replacement
may be necessary.
