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.
If you need to lay the device down while it is out of the antistatic bag, lay it on the antistatic bag. Before
picking it up again, touch the antistatic bag and the metal frame of the system unit at the same time.
Rack Warnings
If you plan to rack mount the AS175, please follow the rack manufacturer's safety instructions.
Install the enclosure only in a rack that has been properly secured in an area with suitable environmental
conditions.
Have someone assist you during physical installation.
To properly ventilate the system, you must provide at least 7.6 cm of clearance at the front and back of the
system.
To reduce the risk of personal injury or damage to equipment, always ensure that the rack is adequately
stabilized prior to extending a component outside the rack. A rack may become unstable if more than one
component is extended. Extend only one at a time.
Do not stand or step on any components in the rack.
