Observe the following precautions for rack stability and safety. Also refer to the rack 
installation documentation accompanying the system and the rack for specific warn-
ing and/or caution statements and procedures.
Server and storage systems are considered to be components in a rack. Thus, “com-
ponent” refers to any server or storage system, as well as to various peripherals or 
supporting hardware.

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.
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.
