Safety Considerations
Before proceeding with any installation, maintenance, or service on a system which 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
Hewlett-Packard system compliance tests are conducted with Hewlett-Packard 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 Hewlett-Packard's instructions minimizes the
chances that the system will cause radio or television interference. However, Hewlett-Packard 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 Hewlett-Packard supported peripheral devices.
• Ensure that all panels and cover plates are in place and secure before system operation.
Electrostatic Discharge
Hewlett-Packard 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.
Take these precautions:
• Always wear a grounded wrist strap when working on or around the system.
• Treat all assemblies, components, and interface connections as static-sensitive.
• When unpacking cards, interfaces, and other accessories that are packaged separately from the system,
keep the accessories in their conductive plastic bags until they are ready to be installed.
• Before removing or replacing any components or installing any accessories in the system, select a work
area where potential static sources are minimized (preferably an anti-static work station).
• Avoid working in carpeted areas, and keep body movement to a minimum while installing accessories.
