vUse only approved tools and test equipment. Some hand tools have handles that are covered with a soft material that does not provide insulation from live electrical currents.

vRegularly inspect and maintain your electrical hand tools for safe operational condition. Do not use worn or broken tools or testers.

vDo not touch the reflective surface of a dental mirror to a live electrical circuit. The surface is conductive and can cause personal injury or equipment damage if it touches a live electrical circuit.

vSome rubber floor mats contain small conductive fibers to decrease electrostatic discharge. Do not use this type of mat to protect yourself from electrical shock.

vDo not work alone under hazardous conditions or near equipment that has hazardous voltages.

vLocate the emergency power-off (EPO) switch, disconnecting switch, or electrical outlet so that you can turn off the power quickly in the event of an electrical accident.

vDisconnect all power before you perform a mechanical inspection, work near power supplies, or remove or install main units.

vBefore you work on the equipment, disconnect the power cord. If you cannot disconnect the power cord, have the customer power-off the wall box that supplies power to the equipment and lock the wall box in the off position.

vNever assume that power has been disconnected from a circuit. Check it to make sure that it has been disconnected.

vIf you have to work on equipment that has exposed electrical circuits, observe the following precautions:

–Make sure that another person who is familiar with the power-off controls is near you and is available to turn off the power if necessary.

–When you are working with powered-on electrical equipment, use only one hand. Keep the other hand in your pocket or behind your back to avoid creating a complete circuit that could cause an electrical shock.

–When you use a tester, set the controls correctly and use the approved probe leads and accessories for that tester.

–Stand on a suitable rubber mat to insulate you from grounds such as metal floor strips and equipment frames.

vUse extreme care when you measure high voltages.

vTo ensure proper grounding of components such as power supplies, pumps, blowers, fans, and motor generators, do not service these components outside of their normal operating locations.

vIf an electrical accident occurs, use caution, turn off the power, and send another person to get medical aid.

Working inside the server with the power on

Attention

Static electricity that is released to internal server components when the server is turned on might cause the server to halt, which might result in the loss of data. To avoid this potential problem, always use an electrostatic-discharge wrist strap or other grounding system when you work inside the server with the power on.
