!

Follow these rules to ensure general safety:

Keep the area around the SuperServer 5015M-UR/5015M-U/5015M-NTR/ 5015M-NT clean and free of clutter.

The SuperServer 5015M-UR/5015M-U/5015M-NTR/5015M-NT weighs approximately 45/42 lbs. (20.5/19.1 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.
