Most appliances can be installed in standard server racks that conform to EIA-310-D specification. The appliances ship with a set of rails, which you must install before you mount the appliance. The only tools that you need for installing an appliance are a Phillips screwdriver and a flathead screwdriver.
To mount the appliance, you must first install the rails and then install the appliance in the rack.
The same rail kit is used for both square-hole and round-hole racks. See figure 4 for specific instructions for threaded, round-hole racks.
If you are installing the appliance as the only unit in the rack, mount it at the bottom. If the rack contains other units, make sure that the heaviest unit is at the bottom. If the rack has stabilizing devices available, install them before mounting the appliance.
