•When connecting or disconnecting power to
—Install the power supply before connecting the power cable to the power supply.
—Unplug the power cable before removing the power supply.
—If the system has multiple sources of power, disconnect power from the sys- tem by unplugging all power cables from the power supplies.
•Move products with care; ensure that all casters and/or stabilizers are firmly con- nected to the computer or storage system. Avoid sudden stops and uneven surfaces.
Precautions for Rack-Mountable Products
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.
Servers, storage systems, and appliances are considered to be components in a rack. Thus, “component” refers to any server, storage system, or appliance, as well as to various peripherals or supporting hardware.
WARNING: Installing Dell system components in a Dell rack without the front and side stabilizers installed could cause the rack to tip over, poten- tially resulting in bodily injury under certain circumstances. Therefore, always install the stabilizers before installing components in the rack.
After installing system/components in a rack, never pull more than one component out of the rack on its slide assemblies at one time. The weight of more than one extended component could cause the rack to tip over and injure someone.
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.
•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.
