Install a rear 2.5-inch drive backplane

Follow instructions in this section to install a 2.5-inch drive backplane. The procedure must be executed by a trained technician.

About this task

Attention
  • Read Installation Guidelines and Safety inspection checklist to ensure that you work safely.
  • Touch the static-protective package that contains the component to any unpainted metal surface on the server; then, remove it from the package and place it on a static-protective surface.
  • Power off the server and peripheral devices and disconnect the power cords and all external cables. See Power off the server.
  • If the server is installed in a rack, slide the server out on its rack slide rails to gain access to the top cover, or remove the chassis from the rack. See Remove the server from rack.
  • 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 server supports one rear 2.5-inch drive backplane with the following corresponding drive backplane numbering.

  • Install air baffle to the rear drive backplane when NVIDIA BlueField-3 B3220 is installed.
Firmware and driver download: You might need to update the firmware or driver after replacing a component.

Procedure

  1. Install air baffle to the rear drive backplane when NVIDIA BlueField-3 B3220 is installed. Remove the liner from the air baffle; then, align and stick the air baffle to the backplane.

  4. Connect all the cables to the rear 2.5-inch drive backplane. See 2.5-inch drive backplane cable routing for more information.
  5. If necessary, attach the labels to both ends of the cable.
    1. Attach the white space portion of the label to one end of the cable.
    2. Wrap the label around the cable and attach it to the white space portion.
    3. Repeat to attach the other label to the opposite end of the cable.
