D10 I/O Backplane Assembly - IBM pSeries 7311 D10 Service Manual

D10 I/O Backplane Assembly

Before performing the following procedure, read the "Safety Considerations" on page 41.
Note: The I/O backplane and the SPCN riser card are replaced as a pair.
Removal
1. Turn off the system power.
2. Put the I/O subsystem into the service position as described in "D10 Service Position" on page 43.
3. Label and remove the PCI adapters. (See "PCI Adapters" on page 45).
4. Remove the service access cover. (See "D10 Covers" on page 44).
5. Disconnect the fan cable from the I/O backplane.
6. Remove the power supplies. (See "D10 Power Supply" on page 111).
7. Remove the RIO bus adapter. (See "D10 RIO Bus Adapter Assembly" on page 109).
8. Remove the two screws that hold the SPCN connector card, and remove it from the I/O backplane.
9. Remove the screws that hold the PCI adapter mounting-guide, and remove the guides from the I/O
backplane.
10. Remove the screws that secure the I/O backplane to the subsystem chassis.
11. Lift the I/O subsystem backplane straight up and out of the subsystem chassis.
Note: If you are replacing the I/O subsystem backplane, mark and remove the VPD module (see
"Model D10 I/O Backplane Locations" on page 12 for VPD module location) from the old
backplane and move it to the replacement I/O subsystem backplane.
Replacement
Note: If the power supplies are not removed from the I/O subsystem chassis, remove them before
replacing the I/O subsystem backplane.
1. Place the I/O subsystem backplane assembly into the chassis. Align the backplane with the mounting
screw holes.
Note: If you are replacing an I/O subsystem backplane with a new one, remove the VPD module
from the old backplane and move it to the replacement I/O subsystem backplane. For VPD
module location, see "Model D10 I/O Backplane Locations" on page 12. Put the module from
the new backplane onto the old backplane.
2. Position the PCI adapter mounting-guides on the I/O backplane, and install the screws to secure the
mounting-guides.
3. Secure the backplane with the remaining mounting screws removed earlier.
4. Reconnect the fan cable to the I/O backplane.
5. Install the new SPCN connector card on the new I/O subsystem backplane using the screws that you
removed earlier.
Note: The I/O backplane and the SPCN connector card are replaced as a pair.
6. Reinstall the RIO bus adapter card. (See "D10 RIO Bus Adapter Assembly" on page 109).
7. Reinstall the power supplies. (See "D10 Power Supply" on page 111).
8. Reinstall the cover. (See "D10 Covers" on page 44).
9. Reinstall all PCI adapters. (See "PCI Adapters" on page 45).
10. Return the I/O subsystem to the operating position (see "D10 Operating Position" on page 43) and
connect RIO, SPCN, and adapter cables.
11. Connect the power cables.
12. Power the system on.
