Working with Adapters
You can add adapters to extend the capabilities and power
of your server. Many adapters provide bus-master
capabilities, which enable the adapters to perform
operations without interrupting the server's
microprocessors. You add adapters to the expansion
connectors, called slots, on the I/O board of your server.
All slots are peripheral component interconnect (PCI)
expansion slots. Your server supports up to 12 adapters
in the PCI slots.
You can install a new PCI adapter or replace an existing
PCI adapter with the same type of adapter without turning
the server power off and restarting the system. These
slots are called
hot-pluggable PCI slots. They are also
referred to as hot-plug PCI slots. Hot-plug requires
support from both the operating system and the adapter
device driver.
A PCI adapter comes with built-in identification and
configuration specifications (set in memory on the device)
that provide installation information to the server during
startup. This information is read by the input/output (I/O)
bus and interpreted by the server BIOS. The BIOS
routines automatically configure the adapter around the
resources already in use by other devices.
Your server comes with a video controller. This video
controller is an integrated component on the I/O function
card. The integrated video controller has super video
graphics array (SVGA) technology.
The integrated video controller is not removable. If you
want to disable this controller and use a video adapter
instead, you can install a video adapter in an expansion
slot. When you install a PCI video adapter, the server
BIOS automatically disables the integrated video controller.
The integrated video controller has 1 MB of video memory.
The integrated video controller supports the following
screen resolutions:
