Step 2:
Mate the transition cards with the ribbon cable edge connectors as indicated
below. Secure the ribbon cable connectors to the transition cards with wire ties.
The tie wrap binding needs to be on the top for an Upper board and on the
bottom for a Lower board for clearance.
Clip wire tie ends for neatness.
Install the New Backplane & Make
Connections
Step 1:
Set the DMX termination switches to
off
.
The switches and their location are
shown here.
Step 2:
Bend one arm of the backplane metal in towards
the opposite arm (about 30 deg). Bend the metal
as little as is possible to get it inside the rack.
Step 3:
Insert the backplane metal on an angle. Then
straighten it once it is past the face of the rack.
Push it into the rack far enough that it stays in
place, but leave yourself some room to make the
power and data connections.
Step 4:
Insert the power connection in the backplane
power header. (Look at the pin shapes for proper
orientation. It will only fit one way.)
Step 5:
Push the backplane the rest of the way into the rack. Be
careful of the power connection you just made. Don’t let
any of the wiring become stressed or get pinched.
Step 6:
Insert tabs in the side of the rack.
Step 7:
With the tabs fully inserted in the sides of the rack, pull the
backplane towards the front of the rack to line up the
screw holes in the upper side corners to line up.
Step 8:
Install one screw with a sleeve
in each side upper-corner of the
backplane.
