Rack mounting brackets

All routers ship with pre-installed mounting brackets that allow you to front-mount the router in a standard 19-inch (EIA310-D) rack. For
instructions about how to mount the router in a rack, refer to the installation chapter that is appropriate for your router model.
You can also mid-mount your 4-, 8- or 16-slot router in a rack using the brackets that ship with the router. You simply remove the
brackets from the front of the router and mount them midway along the sides of the router. For more information, see the installation
chapter appropriated for your router model.
