Step 1542-7
I/O subsystem 1 (U1.9) is the only I/O subsystem connected to the processor subsystem.
1. Turn on the power to boot standalone diagnostics from CD.
2. If the Please define the System Console screen is displayed, follow directions to select the system
console.
3. 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).
4. Check that all attached devices and adapters are listed.
If the Please define the System Console prompt did not display or all attached devices and adapters are
not listed, the problem is in the media subsystem or I/O subsystem 1 (U1.9).
Did the Please define the System Console screen display and are all attached devices and adapters
listed?
NO Go to "Step 1542-8".
YES Go to "Step 1542-21" on page 317.
Step 1542-8
Perform the following to deconfigure the media subsystem:
1. Turn off the power.
2. If you have not already done so, set the service processor settings with the instructions in step 5 on
page 306. Then return here and continue.
3. Exit the service processor menus, and disconnect the power cable between the I/O subsystem 1 right
media subsystem power connector (U1.9-P2-V1/Q3) and the media subsystem.
4. If a display adapter with keyboard and mouse connected to a Keyboard/Mouse Attachment (USB) card
in I/O subsystem 1 (U1.9) is being used as the console, locate a standalone serial terminal (for
example a 3151), and connect to the S1 serial port or use the HMC.
5. Remove the keyboard and mouse, if attached to the I/O subsystem 1 (U1.9).
6. Remove (unplug) the tape drive (if installed) from the media subsystem.
7. Disconnect the diskette drive cable from the diskette drive connector on the media subsystem.
8. Connect the power cable between the I/O subsystem 1 right media subsystem power connector
(U1.9-P2-V1/Q3) and the media subsystem. The media subsystem operator panel momentarily
displays an OK prompt.
9. Set the current drawer location to x.y=1.9. Use this value in future steps until changed in a later step.
