Use this procedure to install the midplane assembly.
This procedure requires removing the server from the rack. Removing all front and back components lessens the weight of the server.
This is a cold-service procedure. Power down the system and disconnect all power cables before removing the server access panels.
Caution - Hazardous voltage. Possibility of electrical shock if the power cables are connected to the server when accessing the midplane and bus bar assembly.
Caution - The midplane assembly should be removed and replaced only by authorized Oracle Service personnel.
Since the midplane contains both A- and B-side Primary FRU containers, when the midplane needs to be replaced, Oracle Service personnel need to manually reprogram the FRU containers into FRUPROM0 and FRUPROM1.
This procedure requires a Phillips screwdriver and a mechanical lift. Do not lift the server manually. Use a mechanical lift instead.
The cables inside the chassis should lie flat, so they are not damaged during the installation of the replacement midplane assembly.
Take care not to damage the cables and connectors when lowering the midplane assembly into the server.
Ensure that the connectors are positioned correctly, so the key (protrusion) on the side of the connector is aligned with the notch in the connector on the midplane assembly. For best access and visibility, first attach the cable labeled PS 0, then PS 2, followed by PS 1, and finally PS 3. Attach the cable for the AC power indicator board last.
The following illustration shows the label.
Ensure that the orientation of the insert is correct. The insert is fitted to the opening using tabs and flaps.

Install data cables (DPCC and SMOD) before attaching AC power cables to the AC inlets.
