General Safety Precautions

Follow these rules to ensure general safety:
Keep the area around the 4020C-T clean and free of clutter.
The 4020C-T weighs approximately 57 lbs (25.6 kg) 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 won't 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.
After accessing the inside of the system, close the system back up and secure
it to the rack unit with the retention screws after ensuring that all connections
have been made.
