Step 1542-20
1. Turn off the power.
2. The part just replaced fixed the problem.
3. If a display adapter with keyboard, and mouse were used, reinstall the display adapter card, keyboard
and mouse.
4. Reconnect the diskette drive cable to the diskette drive connector on the media subsystem.
5. Reconnect the tape drive (if previously installed) to the internal SCSI bus cable.
6. Plug in all adapters that were previously removed but not reinstalled.
7. Reconnect the I/O subsystem power cables that were previously disconnected.
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.
Step 1542-21
If the boot is successful, the problem is with a remaining I/O subsystem. Turn off the power.
Are there any I/O subsystems left to connect to the processor subsystem?
NO 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.
YES Go to "Step 1542-22".
Step 1542-22
Reconnect the next I/O subsystem in the configuration that you recorded earlier in this MAP. Use the
following table to determine the next I/O subsystem to reconnect.

Note: The I/O subsystems should be cabled as shown in "Subsystem Positioning and Cabling" on
page 39.
