Mechanical Recommendations for the Rack
     
    
        Use equipment racks that meet the following mechanical
            recommendations:
        
            - Use an open style, 19-inch rack to facility easy maintenance and to provide proper
                ventilation.
 
            - Use a rack made of steel or aluminum.
 
            - The rack should use the universal mounting rail hole pattern that is identified in
                EIC Standard 297.
 
            - The rack should have designated earth grounding connections (typically on the
                base).
 
            - The rack must meet earthquake safety requirements equal to that of the installed
                chassis.
 
            - The mounting holes should be flush with the rails to accommodate the chassis.
 
            - The rack should support approximately 276 kg (600 lb).
