Attaching the Model 7411–K Junction Box to the VAC/16
To connect a Model 7411–K VAC/16 controller to its J-box assembly(ies), use the
instructions that follow.
NOTE: The illustrations in this section show a Model 7411–K VAC/16 that has not
yet been installed in an AViiON computer chassis. (For ease of assembly,
we recommend that you attach the J-box assembl(ies) before installing a
new or replacement Model 7411–K in your VME card cage.) If your
VAC/16 board is already installed in the card cage, skip Step 1 and follow
steps 2–4 to remove the tension bar, attach the J-box ribbon cables, and
reattach the cable tension bar.
1. After you configure the board as described in Chapter 2, lay it on a static-free
surface with the junction box assembly(ies) you plan to install. See Figure D–4.
Lay out the assembly to avoid working over, and possibly damaging, the board
components.
