Install the Motherboard
Caution - The motherboard should be installed only by an Oracle qualified service technician.
- Attach an antistatic wrist strap.
See Take Antistatic Measures.
- Install the motherboard into the server's chassis .
- To install the motherboard into the server, grasp the middle of the air
duct in the front and back and tilt the front of the motherboard
up slightly and push it into the opening in the rear of the
- Lower the motherboard into the server's chassis and slide it to the rear
until it engages the six mushroom standoffs located on the server's chassis under
- Ensue that the indicators, controls and connectors on the rear of the motherboard
fit correctly into the rear of the server's chassis.
- Install the server's mid-wall .
- Ensure that the cables (SAS and DVD cable, if applicable), are running through
the opening in the center of the mid-wall.
- Position the mid-wall with cables in front of the motherboard so that it
engages the mushroom standoffs that are located on the server's chassis sidewall (one
for each side of the mid-wall).
- Place the FIM cable and the disk backplane power cable along side the
mid-wall next to their respective motherboard connectors.
- Ensure that FIM cable and the disk backplane power cable are not pinched
by the mid-wall and that they run beside the mid-wall and not under
it; otherwise, the cables might be damaged.
- To secure the mid-wall to the server's chassis, tighten the four green captive
- Carefully place the SAS cable(s) that you disconnected from the internal HBA into
the cable trough provided by the air duct on the motherboard.
- If the server has a DVD drive, carefully place the DVD drive cable
into the cable trough provided by the air duct on the motherboard.
- If the server has a DVD drive, reconnect the DVD drive cable to
the motherboard .
- Reconnect the front indicator module (FIM) cable to the motherboard .
- Reconnect disk backplane LED cable to the motherboard .
- Reconnect the disk backplane power cable to the motherboard .
- Reinstall the following reusable components:
- PCIe risers and attached PCIe cards.
For instructions, see Servicing PCIe Risers (CRU).
- Power supplies.
Caution - When reinstalling power supplies, it is important to reinstall them into the slots
from which they were removed during the motherboard removal procedure; otherwise, the server's FRU
top-level indicator (TLI) data might be lost. When a server requires service, the
FRU TLI is used by Oracle to verify that the server's warranty has
not expired. For more information on the server's FRU TLI, see the Administration, FRU TLI Auto-Update
For instructions, see Install a Power Supply.
- Fan modules.
For instructions, see Install a Fan Module.
- Return the server to operation.
- Install the top cover.
See Install the Top Cover.
- Close the server fan door.
- Return the server to the normal rack position.
See Return the Server to the Normal Rack Position.
- Reconnect the data cables and the power cords to the server power supplies.
See Reconnect Data Cables and Power Cords.
- Power on the server.
See Power On the Server.
Verify that the Power/OK indicator is steady on.
Note - IMPORTANT: After replacing the motherboard, you might need to manually program the product serial
number (PSN) into the new motherboard. This is necessary because the motherboard is
a secondary quorum member for maintaining the PSN for service entitlement and if
you replace move than one of the quorum members during any given service
procedure, a secondary quorum member might need to be programmed with PSN.
