Use this procedure to remove 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.
This is a cold-service component. Power down the system and disconnect the AC power cables from the server before performing this procedure.
For fan designations, see and Replaceable Components.
Before removing CMODs, label each module and module slot. Your server might have four CMODs, or it might have eight.
Before removing power supplies, note the AC inlet number.
Before removing cables, label each cable, noting the cable connection point.
Label the SMODs SMOD0 and SMOD1 to ensure that SMOD0 and SMOD1 are returned to their original locations.
Caution - Lifting equipment: Oracle Server X7-8 weighs 114 kg (250 lbs). Only use a mechanical lift to lift and mount the server into the rack enclosure
The midplane assembly is located inside the server. In the following illustration, call out 1 shows the location of the midplane assembly.
Note the orientation of the insert with respect to the opening. The insert is fitted to the opening using tabs and flaps.
The opening behind the access panel provides access to five cables (four 20-pin PS cables and one 8-pin cable for the AC power indicator LEDs) that are routed through the server and are connected to the backside of the midplane assembly. To remove the midplane assembly, disconnect these connectors. As an aid, a label on the side of the chassis shows the arrangement and labeling of the five connectors.
The following illustration shows a portion of the label.
The following illustration shows the label.
The following illustration shows the location and arrangement of the connectors on the back of the midplane.
The cables inside the chassis should lie flat, so they are not damaged during the installation of the replacement midplane assembly.
