Disconnect Cables
1. With the cable retainer in front of you and the part number visible (4B or
4C), locate the slot that is almost vertical. This slot is adjacent to the part
number. Insert a flat blade screwdriver with a 1/4-inch blade into the slot
and twist. The retainer will snap open easily. Remove the cable.
2. Disconnect previously labeled cables associated with the carrier to be
removed.
3. Behind a “DEFINITY style” cabinet, remove the back doors from the
cabinet.
4. Behind a previously upgraded cabinet, remove all of the back panels.
(Two different types of screws hold the back panels to the cabinet. The
#10 screws can be removed with a screwdriver or a 1/4-inch socket. The
#12 screws can be removed with a screwdriver or a 5/16-inch socket.)
