About this task

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

  • Power off the server and peripheral devices and disconnect the power cords and all external cables. See Power off the server.

  • Firmware and driver download: You might need to update the firmware or driver after replacing a component.
  • To install the rails into a rack, follow the instructions that are provided in the Rail installation Guide.
  • Two people and one lifting device on site that can support up to 400 lb (181 kg) are required to perform this procedure. If you do not already have a lifting device available, Lenovo offers the Genie Lift GL-8 material lift that can be purchased at Data Center Solution Configurator. Make sure to include the Foot-release brake and the Load Platform when ordering the Genie Lift GL-8 material lift.
  • The maximum lift height for installation is 156 cm (61.5 inches). The maximum units to be installed on the rack is up to 4 units from the bottom to the top of the rack as illustrated.

After rails are installed successfully, complete the following steps to install the chassis in a rack.

Procedure

  1. Make preparation for this task.
    1. Pull the system shuttle out of the chassis, and place it onto the lift platform. See Remove the system shuttle.
    2. Remove all the power supply units. See Remove a hot-swap power supply unit.
    3. Remove the rear fans (fans 1 to 15). See Remove a hot-swap fan.
  2. Attach four handles to the chassis.

After you finish
  1. Reinstall the rear fans. See Install a hot-swap fan.
  2. Reinstall all the power supply units. See Install a hot-swap power supply unit.
  3. Reinstall the system shuttle. See Install the system shuttle.
  4. Install any other required components.
  5. Reconnect the power cords and any cables that you removed.
    Important
    For any AI rack server that supports up to eight CFF PSUs in the rear of the server and operates with N+N redundancy, the two rack-level AC lines feeds must alternate between the PSUs to ensure balanced power distribution and redundancy.
    • Rack-level AC line feed A: Connect to PSU 1, 3, 5, 7 (odd numbered PSUs)
    • Rack-level AC line feed B: Connect to PSU 2, 4, 6, 8 (even numbered PSUs)
  6. Power on the server and any peripheral devices. See Power on the server.
  7. Update the server configuration. See Complete the parts replacement.
