If you are mounting the BTI7801 into a 4-post 19-inch or ETSI 600-mm cabinet, and

support the rear of the chassis.
Working from the rear of the rack, insert each screw, loosely, through the lock washer
then the flat washer, through the bracket, and finally into the rack post hole. The
support bracket requires four sets of screws, two for each rear post. All screws and
washers are included in the BT8A78SSB3 kit. When all the screws are in place, tighten
