Use distribution racks that meet the following mechanical recommendations:
-
An open style, 19-inch (48.26 cm) rack facilitates easy maintenance and to provide proper ventilation.
-
The rack must use the universal mounting rail hole pattern that is identified in EIA Standard RS-310C (in countries other than the US, use IEC Standard 297).
-
The mounting holes should be flush with the rails to accommodate the chassis.
-
The rack must be made of steel or aluminum.
-
The rack must be able to easily support an additional load of approximately 50 pounds.
