sections in this appendix that apply.
•
If you need to install a Model 7411–KA VAC/16 in your VME card cage, refer to

Attaching an Air Dam to a VFC Controller
Board
You may have received a replacement VFC controller board without the air dam (or
front panel) necessary to install the controller in some AViiON
computers. If so,
you must remove the air dam from the board you are replacing and secure it to the
replacement board before you can install the VFC assembly in your system.
CAUTION: Do not attempt to operate your computer unit without air dams, cover
panels, or filler panels in every VMEbus option slot. Lack of a proper
panel could affect the safety, reliability, and performance of your
AViiON computer system.
The air dam attaches to the board edge opposite the edge with the VME connectors.
If you hold the board with the component side facing you and the VME connectors to
the right, the air dam will attach to the left edge. Be sure the printing on the air
dam is the right way up. If you have the air dam positioned properly, the jacks for
the cable connectors and optical bypass switch will protrude through the holes on
the air dam.
The following steps outline how to exchange VFC boards and air dams.
1. Make certain you are working in an environment free of electrostatic discharge,
as described in your system documentation and the “Avoiding ESD Damage”
section(s) of Chapter 1.
2. Carefully holding the original VFC asembly by its edges, remove the three
screws that secure the air dam to the controller board. (Refer to Figure D–19).
Take care to retain all of the accompanying washers; try to avoid removing the
plastic ejector assembly from the air dam.
