all power cables from the power supplies.
Move products with care; ensure that all casters and/or stabilizers are firmly con-

NOTE: Dell’s servers, storage systems, and appliances 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 agencies. 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 suit-
ability by a certified 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.
