Chapter 5. Fault and Attention LEDs

This chapter contains information about fault and attention LEDs, which assist in identifying failing
components in your system.

Component LEDs

Individual LEDs are located on or near the failing components. The LEDs are located either on the
component itself or on the carrier of the component (for example, PCI adapters and disk drives). LEDs are
either green or amber.
Green LEDs indicate one of two things:
v Electrical power is present.
v Activity is occuring on a link. (The system could be sending or receiving information.)
Amber-colored LEDs indicate a fault or identify condition. If your system or one of the components on your
system has an amber-colored LED turned on or blinking, identify the problem and take the appropriate
action to restore the system to normal.
The following table identifies the location, color and status of your system component LEDs.
