• Elevated ambient temperature - If installed in a closed rack assembly, the operating temperature of the rack environment may be greater than the room ambient temperature. Use care not to exceed the 40°C maximum ambient temperature of the switch. • Reduced air flow - Install the equipment in the rack so that the amount of airflow required for safe operation of the equipment is not compromised. • Reliable earthing - Maintain reliable earthing of rack-mounted equipment. Pay particular attention to the supply connections other than the direct connections to the branch circuit; for example, use of power strips. • Do not mount the equipment with the rear panel facing in the downward position. Installing the Dell ReadyRails System The ReadyRails rack mounting system is provided to easily configure your rack for installation of your switch. You can install the ReadyRails system using the 1U tool-less method or one of three possible 1U tooled methods (two-post flush mount, two-post center mount, or four-post threaded). 1U Tool-less Configuration (Four-Post Square Hole or Unthreaded Round Hole): 1 With the ReadyRails flange ears facing outward, place one rail between the left and right vertical posts. Align and seat the rear flange rail pegs in the rear vertical post flange. In Figure 4-1, item 1 shows how the pegs appear in both the square and unthreaded round holes. 16 Installation
