Combined Locate button and LED (white)
This LED helps identify which module you are working on in a chassis full of servers.

  • Push and release this button to make the Locate LED blink for 30 minutes.

  • When the Locate LED is blinking, push and release this button to make the Locate LED stop blinking.

  • Hold down the button for 5 seconds to initiate a “push-to-test” mode that illuminates all other LEDs for 15 seconds.

  • This LED can also be made to blink from a remote system using the CMM ILOM. Refer to the Sun Blade Storage Module M2 Administration Guide for details.
