and remove a power supply without first releasing the cord retainer and removing the power
cord.)

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.
