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, 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. See Appendix E for more information.
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
