■ Safety Precautions
WARNING:
Potential injury: On-the-job safety is important; therefore, observe the
following safety precautions while you are engaging in any maintenance
activity. Failing to follow these precautions could result in serious injury.
Remove all conductive jewelry, such as watches and rings, before you
service powered-on equipment.
• Avoid electrical shock. Be careful when you work near power connectors and
supplies.
• Power-off the equipment that is being serviced before you remove a field replaceable
unit (FRU) or other component. Remember that dangerous voltages could still be
present in some areas even though power is off.
• Ground all test equipment and power tools.
• Lift objects properly; read the information in “Lifting Techniques.”
• Do not remove, cut, or relocate any floor tiles indiscriminately. Before you
manipulate floor tiles, be sure that you understand the customer’s environment and
receive the customer’s approval. Remember, each situation is different.
• Enforce good housekeeping practices in the equipment area to help prevent fire and
accidents.
Note: Important things to investigate and to be aware of include the use of Halon®
gas, under-the-floor smoke detectors, and cables to other equipment installed
nearby.
