WARNING: Avoiding Burn Injuries. Some parts inside the computer will
be hot. Wait approximately three to five minutes for them to cool down
before touching them.
WARNING: Metallic Particulates. Metallic particulates can be especially
harmful around electronic equipment. This type of contamination may enter the
data center environment from a variety of sources, including, but not limited to,
raised floor tiles, worn air conditioning parts, heating ducts, rotor brushes in
vacuum cleaners or printer component wear. Because metallic particulates
conduct electricity, they have an increased potential for creating short circuits in
electronic equipment. This problem is exaggerated by the increasingly dense
circuitry of any electronic equipment.
Over time, very fine whiskers of pure metal can form on electroplated zinc,
cadmium, or tin surfaces. If these whiskers are disturbed, they may break off
and become airborne, possibly causing failures or operational interruptions. For
over 50 years, the electronics industry has been aware of the relatively rare, but
possible, threat posed by metallic particulate contamination. During recent
years, a growing concern has developed in computer rooms where these
conductive contaminants are formed on the bottom of some raised floor tiles.
Although this problem is relatively rare, it may be an issue within your computer
room. Since metallic contamination can cause permanent or intermittent failures
on your electronic equipment, Hewlett-Packard strongly recommends that your
site be evaluated for metallic particulate contamination before installation of
electronic equipment.
CAUTION: Avoiding Static Electricity. Static electricity can damage
electronic components. Turn OFF all equipment and disconnect the power
cable before installing an accessory card. Don't let your clothes touch any
accessory card. To equalize the static electricity when replacing an
accessory card, rest the accessory card bag on top of the system unit
while you are removing the card from the bag. Handle the card as little as
possible and with care.
CAUTION: Information on Ergonomic Issues. It is strongly recommended
that you read the ergonomics information, available in the "Safety and
Comfort Guide", before using your system. This guide is available on the
Documentation and Utility CD provided with your system, and at
www.hp.com/ergo.
