     b) View the tray disk drive LED location illustration.

     Note: All of the disk drive Amber LEDs will flash.

  2. Remove the back cover if needed.

  3. From the rear, locate the failed fan assembly by checking the fault lights. If a fault is detected, the Amber LED will be on.

     a) Fan assembly "A" is located on the left and fan assembly "B" is located on the right when viewing the CSM/CEM from the rear.

     b) View the fan assembly location illustration.
