DANGER: Observe the following precautions when working on or around your IT rack system:
• Heavy equipment-personal injury or equipment damage might result if mishandled.
• Always lower the leveling pads on the rack cabinet.
• Always install stabilizer brackets on the rack cabinet unless the earthquake option is to be
installed.
• To avoid hazardous conditions due to uneven mechanical loading, always install the heaviest
devices in the bottom of the rack cabinet. Always install servers and optional devices starting
from the bottom of the rack cabinet.
• Rack-mounted devices are not to be used as shelves or work spaces. Do not place objects on top
of rack-mounted devices. In addition, do not lean on rack mounted devices and do not use them
to stabilize your body position (for example, when working from a ladder).
