Removing extra shipment screws The PowerConnect B-RX Series four-slot and eight-slot chassis ships with two extra screws installed in the right side of the chassis. These screws secure the fan tray, protecting it from damage during shipment. You must remove these screws before installing the chassis. Figure 4 shows the location of the screws. To perform this task, you need a #2 Phillips-head screwdriver. 1 2 3 1 Chassis front 2 Shipping screws 3 Chassis rear FIGURE 4 Removing the extra screws used for shipment Mounting a chassis in a rack Follow the steps given below to mount a PowerConnect B-RX Series chassis in a rack. 1. Determine the position of each chassis in the rack, for example, a chassis with the fewest modules on top, a chassis with more modules than the top chassis in the middle, and a fully populated chassis on the bottom. 2. Position two of the four screws for each chassis on the rack (Figure 5) according to the spacings of the keyhole slots on the mounting brackets as shown in Figure 6 (four-slot and eight-slot chassis) or Figure 7 (16-slot chassis). Do not secure the screws completely; leave approximately (.635 cm (1/4 in.) of clearance between the back of the screw head and the rack. 14 PowerConnect B-RX Series Getting Started Guide 53-1001682-03
