2 Installing a Brocade MLXe-4 router

NOTE

Because of the weight of a fully loaded Brocade MLXe-4 router, Brocade recommends mounting it in 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 rack using the factory-installed mounting brackets for either front- or mid-mounts.

Mounting your device in a standard 2-post rack

The factory-installed mounting brackets allow you to front-mount or mid-mount your device in the rack. For a mid-mount, you must remove the factory installed brackets from the front edge of the device 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 the rack. You will also need a #2 Phillips screwdriver. Complete the following steps.

NOTE

When connecting the device to the rack frame, use thread-forming screws and paint-piercing washers.

1.Determine the position of each router in the rack according to the weight of the router. For example, mount the router with the fewest modules near the top of the rack, a router with more modules 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 rack post, as shown in Figure 46. On one side of the rack, the screw should align with the top hole in the mounting bracket. On the other side of the rack, the screw should align with the bottom hole of the mounting bracket. When tightening these screws, leave approximately 1/4 inch of clearance between the back of the screw head and the rack post.

3.Mount the lowest router first. With one person on each side, lift the router and slip the widest part of each keyhole slot on the mounting bracket over the corresponding screw in the rack post. See Figure 47.
