The DL8000 uses electronic modules which fit into a card cage. The
card cage rests inside the cast housing. See Figure 2-5 for a view of the
card cage as it would appear when the housing is opened.
The card cage provides a backplane with sockets for installing a main
processor board, a DC power supply, up to nine process I/O boards, and
up to three communications cards. The card cage (see Figure 2-5)
supports a total of nine boards, in addition to the power supply and the
CPU.
Note: Board placement is critical for I/O assignments during startup.
Refer to Chapter 3, Modules, for further information.
