Safety Considerations
To avoid bodily harm and damage to electronic components, read the following safety and comfort guidelines before unpacking and configuring the cluster components. Heed the following additional warnings and refer to the Preface section titled HP Cluster Platform Documentation to obtain specific information on safety issues for any cluster component:
• Avoiding Electrical Shocks
To avoid electrical shock, do not open the power supplies or any other parts and components that bear a warning label. There are no user-serviceable parts inside.
Only certified technicians should perform the following tasks:
– Adding electrical circuits for the cluster.
– Checking ground paths.
– Measuring voltage levels of completed circuits.
• Laser Radiation
Do not open a CD-ROM reader or DVD reader laser module. There are no user-serviceable parts inside. The laser module should be serviced by service personnel only. Do not attempt to make any adjustment to the laser unit. See the label on the unit for power requirements and wavelength. HP recommends that you read the ergonomics information provided on the documentation CD-ROM before using your system.
• Moving and Stabilizing Racks
To reduce the risk of personal injury or damage to equipment in the cluster racks, do not attempt to move the racks without adequate assistance, due to their height and weight. Also, do not attempt to move a rack on an incline that is greater than 10 degrees from the horizontal. No rack stabilization kits are provided with the cluster. For a multiple-rack installation, ensure that the racks are coupled together using the specified baying kit.
WARNING!  Some HP cluster models contain zero-U power distribution units (PDUs). The PDU is mounted in the side of the rack and you access it by removing the side panel from the rack cabinet. Do not block access to the side panel by placing the rack close to other equipment.
• Removing and Replacing Cluster Components
Many cluster components are not equipped with extendable rail kits and cable management devices. Refer to the cluster documentation for instructions on how to move components in the rack. There are no safety interlocks which prevent the extension of multiple components at the same time. To reduce the risk of personal injury or damage to equipment in the cluster racks, do not attempt to extend more than one component from a rack at a time. The rack might become unstable and tip over if more than one component is extended.
Be careful when pressing component rail release latches and sliding a component into the rack. The slide rails can pinch your fingertips.
If you need to remove more than one component from a rack for any reason, always start from the top of the rack and remove the lightest items first. When reloading the rack, start from the bottom of the rack and replace the heaviest items first.
Refer to the specifications section of the component documentation to find the weight of a component.
• Removing and Replacing Component Covers
For your safety, never remove the cover from a cluster component 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 the computer using its on/off switch, and then remove the power cord before removing the component’s cover. Remove the Power Protection Device cables before any servicing operation. Always replace the cover before switching the component on again.
• Using Cellular Phones and Other Wireless Technology
Cellular telephones and other wireless technology can interfere with the operation of components in the HP Cluster Platform when the racks are opened and components are removed for service. A cellular telephone might emit a particularly strong signal when it is hunting for a signal. Shut off all wireless technology when servicing the cluster.
• Battery Safety Information
There is a danger of explosion if a 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 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 correctly. Returned batteries are accepted free of charge.
• Avoiding Hearing Damage
Your HP Cluster Platform 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 cluster. The cluster documentation contains information that enables you to calculate the sound energy produced by the cluster.
• Avoiding Burn Injuries
Some parts of the cluster or cluster components become hot during normal use. Wait approximately 3–5 minutes after shutting off the components for them to cool down before touching them.
• Avoiding Static Electricity
Static electricity can damage electronic components and cause minor electrical shocks.
Information on Ergonomics
Ergonomics and safety information is provided with all components. HP recommends that you read and ensure that you understand all such information before using a component. Safety and comfort information is provided at the following URL:

Recycling
Shipping an integrated cluster generates far less packaging than the individual components that it contains. However, large clusters use a substantial amount of packaging material that is not reusable. The bulk of the packaging material is recyclable, and is labeled as such. You should plan on providing a number of dumpsters into which this packaging can be sorted and recycled.
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 nonharmful 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 HP Product Recycling Web site:
