Install the enclosure midplane

(Trained service technician only) Use this information to install the enclosure midplane.

disconnect all power
The power-control button on the device and the power switch on the power supply do not turn off the electrical current supplied to the device. The device also might have more than one power cord. To remove all electrical current from the device, ensure that all power cords are disconnected from the power source.

Before you install the enclosure midplane:

  1. Read the Installation Guidelines to ensure that you work safely.

  2. Three people are needed to complete this task.

Complete the following steps to install the enclosure midplane.

  1. Carefully align the enclosure midplane with the guide pins in the enclosure.

  2. Slide the enclosure midplane half way into the enclosure. Put a screwdriver or a stick in the middle of the enclosure midplane so your hands are free.

    • You must hold the enclosure midplane up against the top inside of the enclosure shell and keep the enclosure midplane vertical during installation. If the enclosure midplane is not inserted correctly, the guide pins can contact the enclosure midplane connectors and damage the connector pins.
    • Do not grasp the connectors on the enclosure midplane when you install it in the enclosure. Touching the connectors might damage the connector pins.
    • Make sure that the fan and power controller cable is out of the way when you slide the enclosure midplane into the enclosure.
  3. Connect the two cables back to fan power connectors and fan signal connectors back to the enclosure midplane.
  4. Use one hand to lift the midplane slightly while carefully removing screw driver / stick holding the midplane in the half-in position, then; slide the midplane all the way into the enclosure until it stops.
  5. Tighten the three captive screws that secure the enclosure midplane to the enclosure.
  6. Rotate the top cover inwards.
  7. Tighten the three captive screws on the top cover.

Reassemble the enclosure and program the vital product data (VPD) that is stored on the card. Complete the following steps:
Three trained technicians are needed to complete the enclosure installation/removal task.
  • Two technicians hold front and rear handles at both sides of the enclosure.

  • One technician protects cables from damage.

  1. Carefully put the enclosure into the rack and slide the enclosure until rear handles are near front rack rails; then, remove rear handles at both sides.

  2. Slide the enclosure farther into the rack until front handles are near front rack rails; then, remove front handles at both sides.

  13. Connect any cables that you disconnected from the modules in the rear of the enclosure.
  14. Connect the enclosure to power (see n1200 Enclosure Installation and Service Guide).
  15. Write down new enclosure midplane serial number (for example: Y030UN34B063) and UUID (for example: 2E2B686CC6B311E2907C6EAE8B16A49E).
  16. Update the solution firmware to the latest level (see n1200 Enclosure Installation and Service Guide).
  17. Log in to the web interface (see n1200 Enclosure Installation and Service Guide).
  18. Go to System Information section, click on the Midplane VPD tab.
  19. Update the new enclosure midplane serial number and UUID onto the fan and power controller (see n1200 Enclosure Installation and Service Guide).
  20. Close the release handles on the tray in order to seat the nodes in the enclosure midplane connectors.
  21. Restart any nodes that you shut down. See the documentation that comes with the compute node for detailed instructions.
  22. The fan and power controller is powered-on automatically.
