3. For the Full-length I/O Book, install the supporting brackets and top cover that come with
the book.

seated properly.
5. Rotate the handle all the way up and push it into the server until the handle locks in place.

The Full-length I/O Book can be used in either the I/O Book bays associated with CPU 2 or
CPU 3. You can install up to two Full-length I/O Books.
Note: Due to the extended length of the full-length PCIe adapters, the Full-length I/O Book
adds a 4-inch mechanical extension to the base length dimension of the server.
