Removal
Note: If you are removing a primary I/O book, save the service processor settings so that you can reset
the service processor after replacement. See "Saving and Restoring Service Processor Settings" on
page 710 for information about saving the service processor settings.
1. Turn off power as described in "Powering Off and Powering On the System" on page 779.
2. At the back of the system, remove the safety bars from the I/O books and blanks.
3. To ease replacement, record the connector locations of all cables attached to the I/O book. Disconnect
all of the cables to the I/O book.
4. If the primary I/O book is being replaced, remove all VPD cards from the old primary I/O book and
install them into the new primary I/O book. See "VPD Card" on page 841 for instructions on removing
and replacing the VPD cards.
5. If the primary I/O book is being replaced, locate the backup copy of the service processor settings. If a
backup copy is not available, use the "Save or Restore Hardware Management Policies," in the
"Introduction to Tasks and Service Aids" section of the RS/6000 and Eserver pSeries Diagnostic
Information for Multiple Bus Systems, order number SA38-0509, to back up the service processor
settings saved in NVRAM. If you cannot run the appropriate task, or the service processor settings
were not previously backed up, the service processor settings must be entered manually after the
primary I/O book is replaced.
6. Grasp the blue release latches located at the top and bottom of the memory book between your thumb
and index finger, and press the tabs together. Actuate both blue handles simultaneously until the book
fully unseats from the connector. Pivot the tabs and pull the book straight back.
