Safety Precautions
Technician Notes
•
Only authorized technicians should attempt to repair this equipment.
•
Before installing this system, carefully read all the manuals included with the system.
•
All repair procedures allow only module replacement. Because of the
complexity of the individual boards and sub-assembles, no one
should attempt to make repairs at the component level or make
modifications to any printed wiring board. Improper repairs can create
a safety hazard.
•
To reduce the risk of personal injury from electric shock and hazardous
energy levels, do not exceed the level of repairs specified in these
procedures.
•
The system is designed to be electrically grounded. To ensure proper
operation, plug the AC power cord into a properly grounded AC outlet
only.
Electrostatic Discharge Precautions
•
Electrostatic discharge (ESD) can damage static sensitive devices or
micro circuitry. Proper packaging and grounding techniques are
required to prevent damage.
•
Keep electrostatic-sensitive parts in their containers until they arrive
at a static free work area.
•
Use a wrist strap connected to the work surface as well as properly
grounded tools and equipment
•
Keep the area free of nonconductive materials such as ordinary
plastic tools and foam packing.
•
Avoid touching pins, leads, or circuitry.
•
Always place drives with printed circuit board (PCB) assembly-side down.
•
Grasp cards and boards by the edges. Hold drives by the frame.
Avoid touching the solder joints or pins.
