Important Safety Warnings
Avoiding Electrical Shocks
WARNING To avoid electrical shock, do not open the power supplies. There
are no user-serviceable parts inside.
To avoid electrical shock and harm to your eyes by laser light, do
not open the DVD laser module. The laser module should be
serviced by service personnel only. Do not attempt to make any
adjustment to the laser unit. Refer to the label on the DVD for
power requirements and wavelength. This product is a class I
laser product.
Removing and Replacing the Cover
WARNING For your safety, never remove the system side cover without first
disconnecting the power cord from the power outlet and
removing any connection to a telecommunications network. If a
Power Protection Device is fitted to your system, you must shut
down your computer using its on/off switch, then remove the
power cord before removing the system’s side cover. Remove the
Power Protection Device cables before any servicing operation.
Always replace the side cover before switching the system on
again.
Battery 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.

8
The battery in this system 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 system, 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.
Avoiding Burn Injuries
WARNING Some parts inside the computer will be hot. Wait approximately
three to five minutes for them to cool down before touching
them.
Avoiding Static Electricity
CAUTION Static electricity can damage electronic components. Turn OFF all
equipment 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.
Information on Ergonomic Issues
It is strongly recommended that you read the ergonomics information,
available in the “Working In Comfort” section of this manual, before
using your system.
You can access more extensive ergonomics information by connecting to
HP’s web site: www.hp.com/ergo

9
Recycling Your System
HP has a strong commitment toward the environment. Your HP system
has been designed to respect the environment as much 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 one of HP’s 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
potential toxic substances, these are reduced into non-harmful
components through special chemical processes. If you require more
details about HP’s product take-back program, contact your local dealer
or your nearest HP Sales Office.

Setting Up Your HP zx6000 or rx2600 System
WARNING If you have any doubt that you can lift the system or monitor
safely, do not try to move them without help.
1. Check the materials list shipped with your system to verify that you
have all of the components necessary for setting up your system.
2. If the system is to be used as a desk-side workstation, place the
system in an area with easily accessible power outlets and enough
space for the keyboard, mouse, and any other accessories.
3. If the system is to be used as a rack-mounted server, please refer to
the rack mounting instructions provided with your rack mount
system.
4. Position the system so that its rear connectors are easily accessible.
Installation Tools
No tools are required to set up your system. However, if you plan to
install or replace an accessory inside your system, you will need a T-10
and T-15 Torx screwdriver or a flat-blade screwdriver. Make sure you use
the Electrostatic Discharge equipment (static-free mat, static strap,
anti-static bags, etc.) to prevent damage to the system.
WARNING 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.

Chapter 120
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.
