General Safety Precautions
!
Follow these rules to ensure general safety:
•
Keep the area around the 2027TR-H71RF/H71FRF/H71QRF server clean and
free of clutter.
•
The 2027TR-H71RF/H71FRF/H71QRF server weighs approximately 85 lbs
(38.6kg) 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.
