SuperWorkstation 7047A-73/7047A-T User's Manual
4-2
4-2 General Safety Precautions
Follow these rules to ensure general safety:
• Keep the area around the SuperWorkstation 7047A-73/7047A-T clean and free
of clutter.
• The 7047A-73/7047A-T weighs approximately 64 lbs (29.1 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. Don't use the handles (if installed) to lift the chassis; the
handles should only be used to pull the server out of the rack.
• Place the chassis top cover and any system components that have been re-
moved 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.

• Serverboard Battery: CAUTION - There is a danger of explosion if the onboard
battery is installed upside down, which will reverse its polarities (see Figure 4-1).
This battery must be replaced only with the same or an equivalent type recom-
mended by the manufacturer (CR2032). Dispose of used batteries according to
the manufacturer's instructions.
• DVD-ROM Laser: CAUTION - this server may have come equipped with a
DVD-ROM drive. To prevent direct exposure to the laser beam and hazardous
radiation exposure, do not open the enclosure or use the unit in any uncon-
ventional way.
• Mainboard replaceable soldered-in fuses: Self-resetting PTC (Positive Tempera-
ture Coeffi cient) fuses on the mainboard must be replaced by trained service
technicians only. The new fuse must be the same or equivalent as the one
replaced. Contact technical support for details and support.
