Install a tray in the enclosure

Use this information to install a DWC tray in the enclosure.

About this task

Attention
Attention
For safety reasons, when removing a tray or a PCS, it is highly recommended to use the Genie® Lift™ GL™-8 due to the server’s weight. Lenovo offers the lift with add on fixtures Genie Lift GL-8 Option Kit and GL-8 Kit for N1380 and SC Systems. If no lift tool is available on-site, customers must move the machine to an accessible, powered area before the trained technician arrives and handles reinstallation. Lenovo strongly advises configuring a complete solution for N1380 and SC-Systems with the lift tool and its add-on features via non-racked items.
Important
Mandatory tools for tray removal and installation.
Attention
DO NOT put your hands on the support bars in order to prevent injury.

Procedure

  1. Select the tray bay to install the tray.
    Attention

    • To maintain proper system cooling, do not operate the enclosure without a DWC tray or tray bay filler installed in each tray bay. See the picture below for reference.

    • Start with tray bay 1 when installing trays into the N1380 enclosure.

    • If you are reinstalling a DWC tray that you removed, you must install it in the same tray bay from which you removed it. Some DWC tray configuration information and update options are established according to tray bay number. Reinstalling a DWC tray into a different tray bay can have unintended consequences. If you reinstall the DWC tray into a different tray bay, you might have to reconfigure the DWC nodes in the tray.
  2. Push down the foot pedal to lock the wheel brakes on the rotate fixture cart.

  3. Push the tray into the angle brackets.
    Figure 3. Pushing tray into angle brackets

  4. Open the rotate fixture.
    1. Grab the handle, and hold the handle down with extra force.
      Figure 4. Holding down the fixture handle

    2. Keep holding down the handle. Meanwhile, rotate the latch counterclockwise until it is unlocked. Make sure to unlock the latches on the right and left sides of the fixture.

    3. Hold the handle; then, slowly rotate it upward until it stands vertically.
      Attention
      Make sure you are holding the handle while opening the rotate fixture.

  5. Adjust the fixture guide fence to the SW position (Single Wide). If the guide fence is not in SW position, lift the guide fence, and re-install it to the SW slots.

  6. Move the lift tool assembly next to the rotate fixture cart assembly as shown in the illustration below. Adjust the lift tool so that the lift tool fixture bottom aligns with the rotate fixture bottom, and the sides of both fixtures are in parallel.
    Note
    Rotate the lift tool handle clockwise to raise the fixture; counterclockwise to lower the fixture.

  7. Push down the foot pedal to lock the wheel brake of the lift tool.

  8. Transfer the tray to the lift tool fixture.
    1. Slide the tray to the lift tool fixture until it is partially seated in the lift tool fixture.
    2. Slide the tray all the way into the lift tool fixture until the tray is completely seated in the lift tool fixture.

  9. Move the lift tool assembly to the front of the rack. Make sure the fixture front side is facing the tray back side.
    Figure 11. Lift tool assembly placement in front of the rack

  10. Adjust the lift tool so that the tray aligns with the tray bay in the enclosure.
    Note
    Rotate the lift tool handle clockwise to raise the fixture; counterclockwise to lower the fixture.

  11. Transfer the tray to the tray bay in the enclosure.
    1. Grab the top and bottom parts of the tray.
    2. Slide the tray into the tray bay until only the TOP printing is seen.

  12. Place the tray into the enclosure.
    1. Rotate the tray handles to the open position.
    2. Insert the tray into the tray bay in the enclosure.
    Figure 15. Placing the tray into the enclosure

  13. Insert the tray into the tray bay while tray handles are in the open position.
    1. Rotate the tray handles to the open position.
    2. Push the tray into the enclosure until the handles bump into the enclosure edges.
    Figure 16. Pushing the tray into the enclosure until handles bump into enclosure edges

  14. Push the tray into the enclosure until the tip of the tray handle touches the enclosure. Make sure there is no distance between the enclosure and the tip of the handle.

    Figure 18. Distinguishing correct tray handle position

  15. Rotate the bottom handle for 45 degrees to push the tray slightly into the enclosure. DO NOT rotate the bottom handle all the way in.
    Note
    If the tray does not move into the enclosure as you rotate the bottom handle, the handles are not in correct position. Reinstall the tray until the handles are seated correctly and handle rotation can bring about tray movement.

  16. Rotate both top and bottom handles to the closed position to secure the tray in the enclosure.
    Figure 20. Rotating both tray handles to the closed position

  17. Make sure the tray does not protrude from the enclosure. The surface of the tray front bezel and the enclosure outer frame should be aligned as a flat surface.

Note
After the DWC tray is installed, the XCC in the DWC tray initializes. This process takes approximately 110 seconds. The power LED flashes rapidly, and the power button on the DWC tray does not respond until this process is complete.

  1. Connect all required external cables to the enclosure.
    Note
    Use extra force to connect QSFP cables to the solution.
  2. Press the power buttons to turn on both nodes in the DWC tray.
  3. Make sure that the power LED on the front operator panel is lit continuously, indicating that the each node is receiving power and is turned on.
  4. If you have other trays to install, do so now.

After you finish

  • If this is the initial installation of the DWC tray in the enclosure, you must configure the DWC tray through the Setup Utility and install the DWC tray operating system.

  • If you have changed the configuration of the DWC tray or if you are installing a different DWC tray from the one that you removed, you must configure the DWC tray through the Setup Utility, and you might have to install the DWC tray operating system.

Note
Server and switch cable are routed through the cable retainers on the bottom front support bracket.
