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:

Refer to the specifications section of the component
documentation to find the weight of a component.
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.
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.
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.
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.
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.
Static electricity can damage electronic components and
cause minor electrical shocks.
