Locate the Server Module

To identify a specific server module from others in the modular system, perform the
following steps.

1. Log in to Oracle ILOM on the server module you plan to locate.

2. Type.

The Locator LED on the server module blinks.

3. Identify the server module with a blinking white LED.

4. Once you locate the server module, press the Locator LED to turn it off.

Note –

Alternatively, you can turn off the Locator LED by typing the Oracle ILOM

set /SYS/LOCATE value=off

command.
