Step 3: Connect the new power adapter harness to the backplane power header. Note
the pin shapes for proper orientation. It will only fit one way. You will connect the
old power harness to the adapter in a later step.
Step 4: Push the backplane completely into the rack. Be careful of the power harness
connection you just made. Make sure that the wiring does not become stressed
or pinched.
Step 5: Insert the backplane side tabs into the sides of the rack.
Step 6: 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 corners.
Step 7: Install one screw with a spacer
in the upper-corner of each side
of the backplane.
Step 8: Install the dimmer output ribbon cables.
a: Open the black retaining tabs for each connector until they are at a 45° angle
to the backplane.
b: Press the connectors into
their respective locations
until the tabs lock in place
at a 90° angle to the
backplane. The order of
the ribbon cables is the
same as for the CEM+
backplane (see graphic).
Make sure the proper
side is facing up on
each connector and that
each connector is fully
seated.
N o t e : You cannot use the old screws
without the additional spacer as
they will block the CEM3 from
being fully inserted.
