type recommended by the manufacturer. Dispose of used batteries according

to the manufacturer's instructions.

service technicians only. The new fuse must be the same or equivalent as the

4-2 General Safety Precautions

Follow these rules to ensure general safety:

• Keep the area around the SuperServer 8047R-TRF+/7RFT+ clean and free of

clutter.

• The SuperServer 8047R-TRF+/7RFT+ 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.
