Warning, caution, and important messages
To reduce the risk of personal injury or damage to equipment, heed all warnings and cautions throughout the installation instructions.
To reduce the risk of personal injury or damage to the equipment, be sure that:
- The leveling feet are extended to the floor.
- The full weight of the rack rests on the leveling feet.
- The stabilizing feet are attached to the rack if it is a single-rack installation.
- The racks are coupled together in multiple-rack installations.
- Only one component is extended at a time. A rack may become unstable if more than one component is extended for any reason.
- Observe local occupational health and safety requirements and guidelines for manual material handling.
- Remove all installed components from the frame before installing or moving the frame.
- Use caution and get help to lift and stabilize the frame during installation or removal, especially when the frame is not fastened to the rack.
When lifting the frame with the optional removable handles, always use at least four people to lift the frame into the rack. If the frame is being loaded into the rack above chest level, a fifth person must assist with aligning the frame with the rails while the other four people support the weight of the frame. If you are using a mechanical lift to install the frame, two people are required to install the frame into the rack.
Install the frame starting from the bottom of the rack and work your way up the rack.
These symbols, on power supplies or systems, indicate that the equipment is supplied by multiple sources of power. NOTE:
To reduce the risk of injury from electric shock, remove all power cords to completely disconnect power from the system.

To reduce the risk of electric shock or damage to the equipment, enter a frame or perform service on system components only as instructed in the user documentation.
A risk of electric shock from high leakage current exists. Before connecting the AC supply to the power enclosure, be sure that the electrical outlets are properly grounded (earthed).
Always be sure that equipment is properly grounded and that you follow proper grounding procedures before beginning any installation procedure. Improper grounding can result in ESD damage to electronic components. For more information, see "Electrostatic discharge."
