2Installing a Brocade MLXe-4 routerNOTEBecause of the weight of a fully loaded Brocade MLXe-4 router, Brocade recommends mounting itin a rack before installing the modules and AC power supplies.You can install up to eight Brocade MLXe-4 routers in a standard 19-inch (EIA310-D) two-post rackusing the factory-installed mounting brackets for either front- or mid-mounts.Mounting your device in a standard 2-post rackThe factory-installed mounting brackets allow you to front-mount or mid-mount your device in therack. For a mid-mount, you must remove the factory installed brackets from the front edge of thedevice and install them using the holes in the center-sides of the device. Refer to Figure 47.You will need to provide four standard #12-24 pan-head screws (per router) to secure routers in therack. You will also need a #2 Phillips screwdriver. Complete the following steps.NOTEWhen connecting the device to the rack frame, use thread-forming screws and paint-piercingwashers.1. Determine the position of each router in the rack according to the weight of the router. Forexample, mount the router with the fewest modules near the top of the rack, a router with moremodules near the middle of the rack, and fully populated routers near the bottom of the rack.2. Using the keyhole slots in the router mounting brackets as a guide, align one screw per rackpost, as shown in Figure 46. On one side of the rack, the screw should align with the top hole inthe mounting bracket. On the other side of the rack, the screw should align with the bottomhole of the mounting bracket. When tightening these screws, leave approximately 1/4 inch ofclearance between the back of the screw head and the rack post.FIGURE 46Positioning the mounting screws in rack posts5" 3"1 21 Unequal flange equipment rack 2 Network equipment rack3.
