Choose Front or Center Mounting
You can mount the router into either a center-mount rack, or into front-mount rack, four-post
rack, or cabinet. In general, a center-mount rack is preferable, because the more even
distribution of weight in the center-mount rack provides greater stability. If installing the
router in a front-mount rack, four-post rack, or cabinet, use the shelf that is provided in
the shipping carton to support the router. Before router installation, attach the shelf to the
back of the support posts in a front-mount rack, or to the front side of the rear posts
in a four-post rack or cabinet.
The router is shipped with the mounting ears installed in the center-mounting position,
as shown in Figure 1 and Figure 2. If you are front-mounting the router, use a Phillips
screwdriver to remove the mounting ears from the center-mounting position. Remove the
screws from the two holes on each side of the chassis that are approximately 1.5 in. (3.8 cm)
back from the router faceplate. Install the mounting ears into those holes. If front-mounting
the router, also install the support shelf into the rack before installing the chassis. Attach the
shelf to the rear of the rack’s front posts.
