Onyx Challenge Mezzanine Card Options

 

 
 

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:

Note: 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.

 Mezzanine 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.

Figure 1 Mezzanine Options Available With Two IO4s

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:

  •  up to two long mezzanine option boards
  • up to two short mezzanine option boards
  •  one long and one short mezzanine option board

The following figure shows the optional second IO4 and the potential configurations for additional optional mezzanine boards that might be installed.

 

Mezzanine Options Available With Three IO4s

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:

  • up to two long mezzanine option boards
  • up to two short mezzanine option boards
  • one long and one short mezzanine option board
