NOTE: Dell’s server and storage systems are certified as components for use in Dell’s rack cabinet using the Dell customer rack kit. The final installation of Dell systems and rack kits in any other brand of rack cabinet has not been approved by any safety agen- cies. It is the customer’s responsibility to have the final combination of Dell systems and rack kits for use in other brands of rack cabinets evaluated for suitability by a certi- fied safety agency.
System rack kits are intended to be installed in a Dell rack by trained service tech- nicians. If you install the kit in any other rack, be sure that the rack meets the specifications of a Dell rack.
Do not move large racks by yourself. Due to the height and weight of the rack, Dell recommends a minimum of two people to accomplish this task.
Before working on the rack, make sure that the stabilizers are secure to the rack, extend to the floor, and that the full weight of the rack rests on the floor. Install front and side stabilizers on a single rack or front stabilizers for joined multiple racks before working on the rack.
Always load the rack from the bottom up, and load the heaviest item in the rack first.
Make sure that the rack is level and stable before extending a component from the rack.
Extend only one component at a time from the rack.
Use caution when pressing the component rail release latches and sliding a com- ponent into or out of a rack; the slide rails can pinch your fingers.
After a component is inserted into the rack, carefully extend the rail into a locking position, and then slide the component into the rack.
Do not overload the AC supply branch circuit that provides power to the rack. The total rack load should not exceed 80 percent of the branch circuit rating.
Ensure that proper airflow is provided to components in the rack.
Do not step on or stand on any system/component when servicing other systems/ components in a rack.
