AS2021M-UR+ User's Manual
4-2
4-2 General Safety Precautions
Follow these rules to ensure general safety:
Keep the area around the 2021M-UR+ clean and free of clutter.
The 2021M-UR+ weighs approximately 37 lbs (16.8 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
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.
!
The power supply power cord must include a grounding plug and must be
plugged into grounded electrical outlets.
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
recommended by the manufacturer. 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 unconventional 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.
