1.3 IT Rack Enclosure and Service Enclosure Warnings
• Keep the enclosures in a controlled indoor environment, away from moisture, temperature extremes, flammable
liquids and gasses, conductive contaminants, dust and direct sunlight.
• Leave adequate space at the front and rear of the enclosures for proper ventilation. Do not block, cover or insert
objects into the external ventilation openings of the enclosures.
• The enclosures are extremely heavy. Use caution when handling the enclosures. Do not attempt to unpack, move or
install them unassisted. Use a mechanical device such as a forklift or pallet jack to move the enclosures in the
shipping container.
• Do not place any object on the enclosures, especially containers of liquid, and do not attempt to stack the enclosures.
• Inspect the shipping container and the enclosures for shipping damage. Do not use the enclosures if they are
damaged.
• Leave the enclosures in the shipping container until they have been moved as close as possible to the final
installation location. The casters are designed for minor position adjustments within the final installation area only.
The casters are not designed for moving the enclosures over longer distances.
• The casters are not designed to provide long-term support for the enclosures after final installation. Use the levelers
to provide long-term support.
• Install the enclosures in a structurally sound area with a level floor that is able to bear the weight of the enclosure, all
equipment that will be installed in the enclosures and any other enclosures and/or equipment that will be installed
nearby.
