Onyx/Challenge
Mezzanine Board
Configurations Each Challenge deskside
system comes with one standard IO4 interface board. See Chapter 1 for a
technical overview of the IO4. The first IO4 in the system always supports
either the VME Channel Adapter Module (VCAM) board or the Graphics Channel
Adapter Module (GCAM) board. If you are unsure
of the system’s hardware configuration, enter the hinv command at the
console. You should see something similar to the following: %

The
GCAM board is used only on POWER Challenge systems that have the
visualization console (Extreme) option installed. Each system is
slightly different, but all systems have at least one IO4 installed. The
number of IO4s installed in your system determines the number of HIO
mezzanine option boards it can support. It also determines the type of
mezzanine options you can order. The VCAM or GCAM on the first IO4
precludes you from using “long” mezzanine boards. Long mezzanine boards
stretch nearly to the backplane and do not fit on the IO4 when a VCAM or
GCAM is installed. Table 1 describes some of the HIO mezzanine option
boards and their lengths. Table

Options Available With One IO4 Figure 1 shows the two
possible configurations of the Challenge equipped with a single IO4. In
the standard server configuration, the IO4 uses a VCAM and the IO4 may use
up to two optional short mezzanine boards. With the POWER Challenge
visualization console option and graphics, use of the GCAM allows only one
optional short mezzanine board. Mezzanine

You can always have one
or two short optional mezzanine boards installed on the primary IO4. This
is determined by whether you have the visualization console option
installed in your POWER Challenge system. When you order a second
optional IO4 you can choose the option of having one of the following
mezzanine configurations installed:
The following figure
shows the optional second IO4 and the potential configurations for
additional optional mezzanine boards that might be installed. You can have one or two
short optional mezzanine boards installed on the primary IO4. When you
order a third optional IO4 you can choose the option of having one of the
following mezzanine configurations installed:
