Safety Considerations - HP Cluster Platform Introduction v2010 Introduction Manual

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
to obtain specific information on safety issues for any cluster component:

12 Safety Considerations
"HP Cluster Platform Documentation"
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.
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.
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.
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.
