1. If you are installing the board into a system of interconnected racks, determine the

rack into which you will install the board.

2. Within the selected rack, determine which module (that is, the upper or the lower)

you are going to work on.

3. Determine which XIO slots in the selected module are usable. Figure 1 illustrates the

XIO slots in a processor module.

Depending on the number of Node boards, the count of usable XIO slots in a

module can be 6 or 12. In modules that require the BaseIO board, XIO slots 2–6 or

2–12 are available.
