1 Router modules router can be running while a power supply is being removed and replaced, but the power supply itself should not be connected to a power source. Otherwise, you could be injured, or the power supply or other parts of the router could be damaged. 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 using two L-shaped mounting brackets that come in a mid-mount kit (ordered separately). The mid-mount kit comes with instructions for installing the mounting brackets and mounting the router in a rack. Contact Dell for more information about the mid-mount bracket kit.
