Follow these rules to ensure general safety:
Observe good housekeeping in the area of the system units during and after maintenance.
Place removed covers and other parts in a safe place, away from all personnel, while you service the system unit.
Keep your tool case away from walk areas so that people do not trip over the tool case.
When lifting any heavy object:
Verify that you can stand safely without slipping.
Distribute the weight of the object equally between your feet.
Use a slow lifting force. Never move suddenly or twist when you attempt to lift.
Lift by standing or by pushing up with your leg muscles. This action removes the strain from the muscles in your back. Do not attempt to lift any objects that weigh more than 16 kg (35 lb.) or objects that you think are too heavy for you.
Do not perform any action that causes hazards to the customer or that makes the equipment unsafe.
Before you start the system unit, ensure that other technical support staff and customer personnel are not in a hazardous position.
Do not wear loose clothing that can be trapped in moving parts. Ensure that your sleeves are fastened or rolled up above your elbows. If your hair is long, fasten it.
Insert the ends of your necktie or scarf inside clothing or fasten the necktie or scarf with a nonconductive clip, approximately 8 cm (3 inches) from the end.
Do not wear jewelry, chains, metal-frame eyeglasses, or metal fasteners for your clothing. Metal objects are good electrical conductors.
Remove items from your shirt pocket, such as pens and pencils, that could fall into the server as you lean over it.
Wear safety glasses when you are working in any conditions that might be hazardous to your eyes.
Avoid dropping any metallic objects, such as paper clips, hairpins, and screws into the server.
After service, reinstall all safety shields, guards, labels, and ground wires. Replace any safety device that is worn or defective.
Reinstall all covers correctly before returning the server to service.
Warning:
To prevent access to electrical hazards by unauthorized personnel and to ensure continued compliance with international radiated emissions requirements, tighten all captive screws securely so they cannot be loosened without the use of a tool.
