1.7.2 Safety Precautions While Working with Electricity
Guidelines when working with electrically powered equipment:
•
Locate the Power Off switch for the system being installed or serviced. In the event of an electrical accident,
the user can quickly turn the power off.
•
Disconnect all power by turning the circuit breakers off before:
•
Installing or removing a chassis
•
Working near the power supply
•
Do not work alone if potential hazards exist.
•
Never assume that power is disconnected from a circuit; always check the circuit.
•
Inspect the work area carefully for possible hazards, such as moist floors, moist or wet ground, ungrounded
power extension cables, frayed power cords, and missing safety grounds.
•
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.
1.7.3 Electrostatic Discharge
Electrostatic discharge (ESD) can damage equipment when electronic equipment is handled improperly. ESD
damage can produce total or partial failures in electronic equipment. Follow these ESD-prevention procedures
when handling systems cards and modules. Follow this procedure:
1. Verify that the frame is electrically connected to earth ground.
2. Wear an ESD-preventive device such as a foot strap or wrist strap, ensuring that it makes good contact
with the user’s skin. If a foot strap is being used, the floor must be ESD conductive.
Ensure customer power source for the product is off.
Ensure that fuses A and B on the 9100 are removed.
