   Attention:

   • To maintain proper system cooling, do not operate the NeXtScale n1200 DWC Enclosure Type 5468 without a DWC tray or tray bay filler installed in each tray bay.

   • When you remove the DWC tray, note the tray bay number. Reinstalling a DWC 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 DWC tray into a different tray bay, you might have to reconfigure the DWC tray.

2. Pull the DWC tray out of the NeXtScale n1200 Enclosure until you see the warning icon in the right side of the cover; then, adjust hands and grip tray (~38lb) at sides to carefully pull out of enclosure.
3. Once the DWC tray has been serviced, place the tray back into the original position as soon as possible.
