ReadyNAS 4200 Hardware Manual
General Safety Precautions
Follow these rules to ensure general safety:
•
Keep the area around the ReadyNAS 4200 clean and free of clutter.
•
The ReadyNAS 4200 weighs approximately 82 pounds when fully loaded. When lifting
the system, two people at either end should lift slowly with their feet spread out to
distribute the weight. Always keep your back straight and lift with your legs.
•
Place the chassis top cover and any system components that have been removed away
from the system or on a table so that they will not accidentally be stepped on.
•
While working on the system, do not wear loose clothing such as neckties and
unbuttoned shirt sleeves, which can come into contact with electrical circuits or be pulled
into a cooling fan.
•
Remove any jewelry or metal objects from your body, which are excellent metal
conductors that can create short circuits and harm you if they come into contact with
printed circuit boards or areas where power is present.
•
Onboard battery: This battery must be replaced only with the same or an equivalent type
recommended by the manufacturer. Dispose of used batteries according to the
manufacturer's instructions.
DANGER:
There is a danger of explosion if the onboard battery is installed upside
down, which will reverse its polarities.
•
Main board replaceable soldered-in fuses: Self-resetting PTC (positive temperature
coefficient) fuses on the main board must be replaced by trained service technicians only.
The new fuse must be the same as or equivalent to the one replaced. Contact technical
support for details and support.
