them, to the dealer from whom you purchased your system, or to HP so that they can either be
recycled or disposed of correctly. Returned batteries are accepted free of charge.
7 Avoiding Hearing Damage
Your HP StorageWorks Scalable File Share might exceed local safety requirements for noise. For
your safety and comfort, always use hearing protection if you are going to be within 10 feet of
the equipment.
8 Avoiding Burn Injuries
Some components are hot. Wait approximately 3–5 minutes after shutting off the components
for them to cool down before touching them.
9 Avoiding Static Electricity
Static electricity can damage electronic components and cause minor electrical shocks.
10 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 exacerbated 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, concern has grown about the threat of this type of contamination 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. Because
metallic contamination can cause permanent or intermittent failures on your electronic equipment,
HP strongly recommends that your site be evaluated for metallic particulate contamination
before installation of electronic equipment.
11 Recycling Your System
HP has a strong commitment to protecting the environment. Your HP system has been designed
to be as environmentally safe as possible. HP can also take back your old system for recycling
when it reaches the end of its useful life. HP has a product take-back program in several countries.
The collected equipment is sent to HP recycling facilities in Europe or the U.S.A. As many parts
as possible are reused. The remainder is recycled. Special care is taken for batteries and other
potentially toxic substances; these are reduced into non-harmful components through special
chemical processes. If you require more information about the HP product take-back program,
contact your local dealer or your nearest HP Sales Office. Further information is also available
on the following HP product recycling Web site:
