Rack mount cases are designed to fit into standard 19-inch racks. They can hold any electronic module, such as power units and disc players. They mount vertically onto metal rails on the sides of each shelf. Some cases fit into half a rack unit, others fill an entire unit, while others span two or more units.
Types of Rack Mount Cases
Kinds of Rack Mount Cases include the following:
Hard-mount rack cases
Hard-mount rack cases are placed on the rack unit with the walls directly touching the case.
They are ideal for mounting interconnected devices, such as multiple power modules for UPS systems.
Shock-mount rack cases
Shock-mount rack cases have a one- to two-inch foam layer between the case and the rack walls.
They are designed for delicate equipment such as lead-acid battery modules and optical drives.
Choosing Rack Mount Cases (Buying tips)
Materials: Choose a rack mount case made of heavy-duty steel or aluminum. Steel is usually more expensive, but aluminum cases have better cooling capacities and may be better for heat-generating equipment, such as power modules.
Mounting: Choose a rack mount case that matches the mounting rails on the rack. Most racks require bolts to support the case. If the rack has square-holed rails, your case must be secured with cage nuts.
