As shown in Figure 3-25, the Primary I/O Book has an internal USB port for the embedded
hypervisor.
The Primary I/O Book also has a large plastic air baffle inside (the baffle is raised on a hinge
in Figure 3-25), which routes hot air from the Storage Book through the two fans in the
Primary I/O Book.
The dedicated IMM2 systems management port is a dedicated Gigabit Ethernet port that
connects to the IMM2. This port is useful if you have an isolated management network. If you
conduct management activities over your production network, you may want instead to use
Port 1 of the ML2 adapter, which can be shared between the operating system and IMM2.
The x3950 X6 has two Primary I/O Books. The second video, IMM2 and internal USB
hypervisor ports are only used when the x3950 X6 is partitioned into two four-socket servers.
The Primary I/O Book is not hot-swappable component of the server.

3.13 Half-length I/O Books and Full-length I/O Books

The Half-length I/O Books and Full-length I/O Books, collectively referred to as Optional I/O
Books, each add three PCIe slots to the server.
Like the Primary I/O Book, the Optional I/O Books are also installed from the rear side of the
server. Figure 3-26 shows the locations of the Optional I/O Books in the x3850 X6 server.
As shown in Figure 3-23 on page 85, the Optional I/O Books require certain processors
(Compute Books) to be installed:
The I/O Book in bay 1 requires processor 4 be installed
The I/O Book in bay 2 requires processor 3 be installed
