Installing the half-length and full-length I/O books
Use this information for an overview of the supported I/O books.
About this task
The server provides up to twelve PCIe Gen3 adapter slots using the supported I/O
books. The server supports an optional half-length I/O book and an optional
full-length I/O book. You install both I/O books in the rear of the server. For more
information about the supported I/O books, see “Installing the half-length I/O
book” and “Installing the full-length I/O book” on page 82.
To confirm that the server supports the I/O book that you are installing, see
http://www.ibm.com/systems/info/x86servers/serverproven/compat/us/.
For more information about the supported adapters, see “Supported RAID
adapters” on page 87 for more information about the supported RAID adapters.
For more information about the supported Ethernet adapters, see “Supported ML2
(Ethernet) adapters” on page 89. For more information about the supported RAID
cache cards, see Table 26 on page 88. For more information about the supported
Features on Demand (FoD) software, see Table 28 on page 92.
Installing the half-length I/O book
This information provides notes and other information that you need to consider
when you install the half-length I/O book and the instructions for installing the
I/O book in the server.
About this task
The following notes provide information that you must consider when you install
the half-length I/O book.
v For additional information about the supported adapters, see “Adapter
installation instructions” on page 92, “Supported ML2 (Ethernet) adapters” on
page 89, “Supported RAID adapters” on page 87, “Supported RAID cache cards”
on page 88, and “Supported host bus adapters” on page 86.
v
The half-length I/O book is hot-swappable if no adapters are installed in the
I/O book. However, if adapters are installed in the I/O book, you must first
press the
Power button on the I/O book and power-off all three PCIe slots
before you remove the I/O book from the server. The slots LED lights will be off
when the slots are off-line.
v
You can remove and install PCIe adapters in this I/O book without powering off
the server.
v
This I/O book supports Gen3 half-length adapters, which are either full-height
or low profile.
v
When this I/O book is installed in the server, it connects to compute book 3 or
compute book 4. See Table 22 on page 81 for more information.
v You can install up to two half-length I/O books in the server.
v
You can also install one half-length I/O book and one full-length I/O book in
the server.
v
For additional about this I/O book, see “Half-length I/O book” on page 35.
The following table lists the I/O book PCIe slot numbering and the slots associated
with each compute book (when two I/O books are installed):
