Safety Warnings, Recommendations, and Tools Required
This chapter describes the safety warnings, recommendations, and tools required to install feature cards in the chassis. This chapter contains the following sections:
•Maintaining Safety with Electricity
•Preventing Electrostatic Discharge
•Required Tools and Equipment
•Where to Go Next
Any device that uses electricity must be handled carefully; follow these guidelines to ensure general safety:
•Keep the chassis area clear and dust-free during and after installation.
•Put the removed chassis cover in a safe place.
•Keep tools away from walk areas where you and others could fall over them.
•Do not wear loose clothing that could get caught in the chassis. Fasten your tie or scarf and roll up your sleeves.
•Wear safety glasses if you are working under any conditions that might be hazardous to your eyes.
•Do not perform any action that creates a potential hazard to people or makes the equipment unsafe.
Warning Ultimate disposal of this product should be handled according to all national laws and regulations. Statement 1040
Maintaining Safety with Electricity
Warning Before working on equipment that is connected to power lines, remove jewelry (including rings, necklaces, and watches). Metal objects will heat up when connected to power and ground and can cause serious burns or weld the metal object to the terminals. Statement 43
Follow these guidelines when you work on equipment powered by electricity.
•Locate the emergency power-OFF switch for the room in which you are working. Then, if an electrical accident occurs, you can act quickly to turn OFF the power.
•Before working on the system, unplug the power cord.
•Disconnect all power before doing the following:
–Installing or removing a feature card
–Working near power supplies
Warning When installing or replacing the unit, the ground connection must always be made first and disconnected last. Statement 1046
•Do not work alone if potentially hazardous conditions exist.
•Never assume that power is disconnected from a circuit. Always check.
Warning Read the installation instructions before connecting the system to the power source. Statement 1004
•Look carefully for possible hazards in your work area, such as moist floors, ungrounded power extension cables, frayed power cords, and missing safety ground connections.
•If an electrical accident occurs, proceed as follows:
–Use caution; do not become a victim yourself.
–Turn OFF power to the system.
–If possible, send another person to get medical aid. Otherwise, assess the condition of the victim and then call for help.
–Determine if the person needs rescue breathing or external cardiac compressions; then take appropriate action.
Warning This product relies on the building's installation for short-circuit (overcurrent) protection. Ensure that a fuse or circuit breaker no larger than 120 VAC, 15A U.S. (240 VAC, 10A international) is used on the phase conductors (all current-carrying conductors). Statement 13
Preventing Electrostatic Discharge
Electrostatic discharge (ESD) can damage equipment and impair electrical circuitry. ESD damage occurs when electronic components are improperly handled and can result in complete or intermittent failures.
Always follow ESD-prevention procedures when you remove and replace components. Ensure that the chassis is electrically connected to earth ground. Wear an ESD-preventive wrist strap, ensuring that it makes good skin contact. Connect the grounding clip to an unpainted surface of the chassis frame to safely ground unwanted ESD voltages. To guard against ESD damage and shocks, the wrist strap and cord must operate properly. If no wrist strap is available, ground yourself by touching the metal part of the chassis.
For safety, periodically check the resistance value of the antistatic strap, which should be between 1 and 10 megohm (Mohm).
