Installing the DS-16B2 Rails Round-Hole Channel Follow the steps below to install the rails assembly in the round-hole channel of the rack/cabinet. 1. Align the holes of the front rail flange to the inside of the front channel. The top and bottom screw holes are used for the screws; the center screw hole is used for the ball stud. 2. Secure the rail to a round-hole channel with 2 M5 x 10-mm panhead screws (see table on page 8). Leave the screws finger-tight, and tighten them after the switch is installed. See Figure 12. 3. Position the #10 flat washer and ball stud in the center hole, between the two M5 x 10-mm screws. Hand-tighten the ball stud. NOTE: The ball studs support the bezel. 4. Align the holes in the rear, U-shaped flange of the rail with the holes in the rear inside channel. 5. Secure the rail to a round-hole channel with 2 M5 x 10-mm panhead screws (see table on page 8).
