2. Remove the screws from the left and right sides of the case. If the rack ears are fitted, there will be

5. Use a Phillips head screw to secure the connector board to the standoff below it and put a dab of
silicone caulk on the screw to hold it in place. Next, make sure that connector J5 is bent out at a
slight angle; this is to ensure that the phantom power cable will clear the top cover.
