Safety and Environmental Considerations

Safety and Environmental Considerations
WARNING Before proceeding with any installation, maintenance, or service on a system that
requires physical contact with electrical or electronic components, be sure that
either power is removed or safety precautions are followed to protect against
electric shock and equipment damage. Observe all WARNING and CAUTION labels
on equipment. All installation and service work must be done by qualified personnel.

Communications Interference

HP system compliance tests are conducted with HP supported peripheral devices and shielded cables, such as
those received with the system. The system meets interference requirements of all countries in which it is
sold. These requirements provide reasonable protection against interference with radio and television
communications.
Installing and using the system in strict accordance with HP instructions minimizes the chances that the
system will cause radio or television interference. However, HP does not guarantee that the system will not
interfere with radio and television reception.
Take these precautions:
• Use only shielded cables.
• Install and route the cables per the instructions provided.
• Ensure that all cable connector screws are firmly tightened.
• Use only HP supported peripheral devices.
• Ensure that all panels and cover plates are in place and secure before system operation.

Electrostatic Discharge

HP systems and peripherals contain assemblies and components that are sensitive to electrostatic discharge
(ESD). Carefully observe the precautions and recommended procedures in this manual to prevent component
damage from static electricity.
CAUTION Connect to ground with a wrist strap. Connection may be made to any grounded metal
assembly in the cabinet. Both you and the electronic devices must be grounded to avoid static
discharges that can cause damage.
Take these precautions:
• Prepare an ESD-safe work surface large enough to accommodate the various assemblies handled during
the upgrade. Use a grounding mat and an anti-static wrist strap, such as those included in the ESD Field
Service Kit (A3024-80004).
• The anti-static bag cannot function as a static dissipating mat. Do not use the anti-static bag for any
other purpose than to enclose a product.
• Treat all assemblies, components, and interface connections as static-sensitive.
