Adding or replacing a graphics controller
(550 series)
This section explains how to add a new or replace a failed graphics
board in an AViiON 550 series computer unit. If your computer
system has a graphics board, you will need to remove it to replace a
failed system board.
The graphics board plugs into interboard connectors on the system
board; these same interboard connectors are used for optional
expansion I/O boards, as described in the next section.
If your workstation uses an 8–bit graphics controller, one option slot
remains for an I/O expansion board; the 8–bit (base unit) controller
uses the bottom option slot. If your workstation has 24–bit graphics,
you cannot add an I/O expansion board; the 24–bit graphic
controller uses both option slots
Figure 7–15 shows the system board locations for the 8– and 24–bit
graphics boards.
