Safety and Environment Considerations
Safety and Environment 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.
