The Retrofit

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.
