Step 1542-5
There are missing devices associated with one or more I/O subsystems.
Note:
Before continuing, check the cabling from the processor subsystem to I/O subsystem(s) to ensure
that the system is cabled correctly. Refer to “Subsystem Positioning and Cabling” on page 37 for
valid configurations. Record the current cabling configuration and then continue with the following
steps:
1. Turn off the power.
2.
At the primary I/O book, disconnect the cable connection at RIO port A0 (U1.18-P1-H2/Q1).
3. Disconnect the cable connection at I/O subsystem 1 left I/O port connector 0 (U1.9-P1/Q2). The RIO
cable that was connected to RIO port A0 should now be loose and can be removed.
4. At the primary I/O book, disconnect the cable connection at RIO port A1 (U1.18-P1-H2/Q2) and
reconnect it to RIO port A0 (U1.18-P1-H2/Q1).
5. Disconnect the cable connection at I/O subsystem 1 right I/O port connector 1 (U1.9-P2/Q1). The RIO
cable that was connected to RIO port A0 on the primary I/O book should now be loose and can be
removed.
6. Verify that processor subsystem RIO port A0 on primary I/O book (U1.18-P1-H2/Q1) is connected to
I/O subsystem 1 left I/O port connector 0 (U1.9-P1/Q2).
7. Verify that I/O subsystem 1 left I/O port connector 1 (U1.9-P1/Q1) is connected to I/O subsystem 1
right I/O port connector 0 (U1.9-P2/Q2).
8. Turn on the power to boot standalone diagnostics from CD.
9. If the Please define the System Console screen is displayed, follow directions to select the system
console.
10. 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
if necessary).
11. 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
listed?
NO
Go to “Step 1542-6” on page 265.
YES
The RIO cable that was removed in step 5 above is defective. Replace the RIO cable. Connect
the new RIO cable from I/O subsystem 1 right I/O port connector 1 (U1.9-P2/Q1) to processor
subsystem RIO port A1 on primary I/O book (U1.18-P1-H2/Q2). Reconfigure the system to its
original condition. Go to “MAP 0410: Repair Checkout” in the
RS/6000 and
