Environmental considerations 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 might cause radio or television interference. However, HP does not guarantee that the system does not interfere with radio and television reception. Take these precautions: • Use only shielded cables. • Install and route the cables according to the instructions provided. • Ensure that all cable connector screws are firmly tightened. • Use only HP supported peripheral devices. • Before system operation, ensure that all panels and cover plates are in place and secure. Preventing electrostatic discharge To prevent damaging the system, be aware of the precautions you need to follow when setting up the system or handling parts. A discharge of static electricity from a finger or other conductor may damage system boards or other static-sensitive devices. This type of damage may reduce the life expectancy of the device. To prevent electrostatic damage: • Avoid hand contact by transporting and storing products in static-safe containers. • Keep electrostatic-sensitive parts in their containers until they arrive at static-free workstations. • Place parts on a grounded surface before removing them from their containers. • Avoid touching pins, leads, or circuitry. • Always be properly grounded when touching a static-sensitive component or assembly. Grounding methods to prevent electrostatic discharge Several methods are used for grounding. Use one or more of the following methods when handling or installing electrostatic-sensitive parts: • Use a wrist strap connected by a ground cord to a grounded workstation or computer chassis. Wrist straps are flexible straps with a minimum of 1 megohm ±10 percent resistance in the ground cords. To provide proper ground, wear the strap snug against the skin.

Environmental considerations
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
might cause radio or television interference. However, HP does not guarantee that the system does not
interfere with radio and television reception.
Take these precautions:
•
Use only shielded cables.
•
Install and route the cables according to the instructions provided.
•
Ensure that all cable connector screws are firmly tightened.
•
Use only HP supported peripheral devices.
•
Before system operation, ensure that all panels and cover plates are in place and secure.
Preventing electrostatic discharge
To prevent damaging the system, be aware of the precautions you need to follow when setting up the system
or handling parts. A discharge of static electricity from a finger or other conductor may damage system
boards or other static-sensitive devices. This type of damage may reduce the life expectancy of the device.
To prevent electrostatic damage:
•
Avoid hand contact by transporting and storing products in static-safe containers.
•
Keep electrostatic-sensitive parts in their containers until they arrive at static-free workstations.
•
Place parts on a grounded surface before removing them from their containers.
•
Avoid touching pins, leads, or circuitry.
•
Always be properly grounded when touching a static-sensitive component or assembly.
Grounding methods to prevent electrostatic discharge
Several methods are used for grounding. Use one or more of the following methods when handling or
installing electrostatic-sensitive parts:
•
Use a wrist strap connected by a ground cord to a grounded workstation or computer chassis. Wrist
straps are flexible straps with a minimum of 1 megohm
±
10 percent resistance in the ground cords. To
provide proper ground, wear the strap snug against the skin.
