Step 1542-28

1. Turn off the power.

2. Slide the secondary I/O book (U1.18-P1-H4) all the way into the processor backplane until it is firmly

seated and latched.

3. At the secondary I/O book, disconnect the cable connection at RIO port D0 (U1.18-P1-H4/Q6).

4. At the secondary I/O book, disconnect the cable connection at RIO port D1 (U1.18-P1-H4/Q5).

5. At the secondary I/O book, disconnect the cable connection at RIO port C0 (U1.18-P1-H4/Q8).

6. Disconnect the cable connection at I/O subsystem 7 left I/O port connector 0 (U2.13-P1/Q2). The RIO

cable that was connected to RIO port C0 should now be loose and can be removed.

7. At the secondary I/O book, disconnect the cable connection at RIO port C1 (U1.18-P1-H4/Q7) and

reconnect it to RIO port C0 (U1.18-P1-H4/Q8).

8. Disconnect the cable connection at I/O subsystem 7 right I/O port connector 1 (U2.13-P2/Q1) and

reconnect it to I/O subsystem 7 left I/O port connector 0 (U2.13-P1/Q2).

9. Verify that processor subsystem RIO port C0 on secondary I/O book (U1.18-P1-H4/Q8) is connected

to I/O subsystem 7 left I/O port connector 0 (U2.13-P1/Q2).

10. Verify that I/O subsystem 7 left I/O port connector 1 (U2.13-P1/Q1) is connected to I/O subsystem 7

right I/O port connector 0 (U2.13-P2/Q2).

11. Turn on the power to boot standalone diagnostics from CD.

12. If the Please define the System Console screen is displayed, follow directions to select the system

13. Use the Display Configuration and Resource List to list all attached devices and adapters (refer to the

RS/6000 and Eserver pSeries Diagnostic Information for Multiple Bus Systems, order number

SA38-0509, if necessary).

14. Check that all attached devices and adapters are listed.

Did the Please define the System Console screen display and are all attached devices and adapters

Connect the previously removed RIO cable from I/O subsystem 7 right I/O port connector 1

(U2.13-P2/Q1) to processor subsystem RIO port C1 on secondary I/O book (U1.18-P1-H4/Q7). Go

to "Step 1542-9" on page 267.

The RIO cable that was removed in step 6 is defective. Replace the RIO cable. Connect the new

RIO cable from I/O subsystem 7 right I/O port connector 1 (U2.13-P2/Q1) to processor subsystem

RIO port C1 on secondary I/O book (U1.18-P1-H4/Q7). Reconfigure the system to its original

condition. Go to "MAP 0410: Repair Checkout" in the RS/6000 and Eserver pSeries Diagnostic

Information for Multiple Bus Systems.
