    Attention:
    • To maintain proper system cooling, do not operate the Lenovo NeXtScale n1200 Enclosure Type 5468 without a water-cooled technology tray or tray bay filler installed in each tray bay.
    • When you remove the water-cooled technology tray, note the tray bay number. Reinstalling a water-cooled technology tray into a different tray bay from the one it was removed from can have unintended consequences. Some configuration information and update options are established according to tray bay number. If you reinstall the water-cooled technology tray into a different tray bay, you might have to reconfigure the water-cooled technology tray.
  2. Pull the water-cooled technology tray out of the tray bay.
  3. Once the water-cooled technology tray has been serviced, place the tray back into the original position as soon as possible.

If you are instructed to return the water-cooled technology tray, follow all packaging instructions, and use any packaging materials for shipping that are supplied to you.
