hp workstations zx6000, hp server rx2600 - operation and maintenance guide

10
CAUTION Both the zx6000 and rx2600 systems depend on the system cover for proper cooling of
internal components. Operating the system with the system cover removed, can cause
the system to quickly overheat.
Safety Information
WARNING There is a danger of explosion if the battery is incorrectly installed. For your
safety, never attempt to recharge, disassemble, or burn an old battery. Replace
the battery with the same or equivalent type, as recommended by the
manufacturer.
The battery in this PC is a lithium battery that does not contain any heavy
metals. However, to protect the environment, do not dispose of batteries in
household waste. Return used batteries either to the shop from which you
bought them, to the dealer from whom you purchased your PC, or to HP so that
they can either be recycled or disposed of in the correct way. Returned
batteries will be accepted free of charge.
Static Electricity
CAUTION Static electricity can damage electronic components. Turn OFF all equipment when
removing or adding components. Don’t let your clothes touch the accessory. To equalize
the static electricity, rest the accessory bag on top of the system while you are removing
the accessory from the bag. Handle the accessory as little as possible and with care.
Potential Metallic Particulate Contamination
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 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.
