D10 I/O Backplane Assembly

Before performing the following procedure, read the "Safety Considerations" on
page 53.
Note: The I/O backplane and the SPCN riser card are replaced as a pair.
Removal
1. Turn off the system power.
2. Perform the procedure to put the I/O subsystem into the service position as
described in "D10 Service Position" on page 57.
3. Label and remove the PCI adapters. (See "D10 PCI Adapters" on page 61).
4. Remove the service access cover. (See "D10 Covers" on page 59).
5. Disconnect the fan cable from the I/O backplane.
6. Remove the power supplies. (See "D10 Power Supply" on page 123).
7. Remove the RIO bus adapter. (See "D10 RIO Bus Adapter" on page 121).
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

Note: If the power supplies are not removed from the I/O subsystem chassis, remove
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
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 removed earlier.
