Remove a DWC tray from the enclosure

Use this information to remove a DWC tray from the enclosure.

About this task


For your safety, use the lift tool to remove the tray from the rack.

  • Read Installation Guidelines and Safety inspection checklist to ensure that you work safely.

  • Turn off the corresponding DWC tray that you are going to perform the task on.

  • Disconnect all external cables from the enclosure.

  • Use extra force to disconnect QSFP cables if they are connected to the solution.


Shared I/O configuration requires specific power on and power off sequence for the two nodes, see below:

  • Power on sequence: first, power on the node with main adapter (right node); then, power on the node with auxiliary adapter (left node).

  • Power off sequence: first, power off the node with auxiliary adapter (left node); then, power off the node with main adapter (right node).

The following illustration might differ slightly from your hardware, but the removal method is the same.


  1. Remove the tray.
    1. Rotate the front cam handles as shown in the illustration. The tray moves out of the tray bay approximately 0.6 cm (0.25 inch).
    2. Pull the DWC tray out of the enclosure until you see the warning icon in the right side of the cover; then, adjust hands and grip tray (~49 lb.) at sides to carefully pull out of enclosure.

    • To maintain proper system cooling, do not operate the enclosure without a DWC tray or tray bay filler installed in each tray bay. For more information, see Install a DWC tray in the enclosure.

    • 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. Once the DWC tray has been serviced, place the tray back into the original position as soon as possible.
