This appendix contains information about the locations and behaviors of the status and fault LEDs on the server. The information is organized to describe external LEDs that can be viewed on the outside of the server, and internal LEDs that can be viewed only with the main cover removed.
This appendix contains the following sections:

Press to toggle on/off locally. Remains on (as fast blinking 4Hz) for 30 minutes or until turned off.
Operators can turn this LED on remotely to help them locate the server in a crowded server room:
- In the ILOM GUI, navigate to System Monitoring > Indicators and select the radio button next to /SYS/LOCATE. From the Actions drop-down menu, select “Set LED to Fast Blink” or “Turn LED Off.”
- In the CLI, enter:
set /SYS/LOCATE value=[fast_blink|off]
- Press to turn on or off.
Press the Locate LED/Switch for five seconds to turn all indicators on for 15 seconds.

C.2 Disk Drive and Fan Tray LEDs
FIGURE C-3 shows the location of the internal LEDs. FIGURE C-5 shows a close-up view of the disk drive and fan trays, including the symbols that identify the LEDs.
| Note - On fan trays, the green and amber (OK and Fault) LEDs might be on simultaneously. This indicates that while a fan has failed, at least one of its fans is still operational.
|
| Note - Early fan trays had a blue LED that was not activated. Later versions of the fan trays have only a green and amber LED.

C.2.1 CPU Board LEDs
The CPU board has three types of LEDs. They are listed in TABLE C-3 and appear in FIGURE C-6.
The CPU LEDs are active only when the Remind button is depressed. They blink to indicate a failure; otherwise they stay Off.
| Note - The CPU and DIMM LEDs continue to indicate a failure until the system is powered on. The Battery LED continues to indicate a failure until the service processor is started.
