Replacing the full-length I/O book
This information provides an overview of the full-length I/O book.
Notes:
• For notes and information that you must consider when you install this I/O book, see "Installing the full-
length I/O book" on page 80.
• If you are replacing the full-length I/O book with a half-length I/O book, see "Installing the half-length I/O
book" on page 79.
• The ability to hot-add the full-length I/O book is dependent on the operating system. If the operating
system does not support hot-plug, the addition or removal of a full-length I/O book might cause an
unrecoverable system error.
Attention:
– If the I/O bay is not populated with a full-length I/O book when the operating system boots or the
operating system is still running, a full-length I/O book cannot be hot-added to the I/O bay (due to
insufficient resources).
– If the I/O bay has a full-length I/O book installed when the operating system boots, you can hot-swap
the full-length I/O book.
To replace the full-length I/O book, complete the following steps:
Step 1. Reinstall the adapters (see "Installing an adapter" on page 83).
Step 2. Close the adapter retention lever.
Step 3. Replace the I/O book cover.
Step 4. Align the I/O book with the I/O bay on the server and slide it into the server.
