NOTE Site Preparation Guidelines Preparing for Installation protection for safety of personnel and to protect computer systems. In the United States (USA), the installation of lightning or surge arrestors on power and communication lines is described in the National Electrical Code, Article 280. The principles of lightning protection and personnel safety are outlined in detail in the lightning protection code contained in the National Fire Protection Association (NFPA) Handbook. The Hewlett-Packard CE can make lightning protection equipment recommendations. Vibration Continuous vibration can cause a degradation of mechanical parts. Vibration can cause data loss on disc drives. Mechanical connections on printed circuit assemblies, connectors, cables, and backplane wiring can also be adversely affected by vibration. If you suspect that vibration may be a problem at your computer site, contact your Hewlett-Packard CE or local sales office for assistance. Electromagnetic Interference The J Class workstation is specifically designed for reduced susceptibility to radiated and conducted interference. Electromagnetic interference can cause a variety of computer system problems. The Hewlett-Packard CE can advise you about many of the most common causes of electromagnetic interference. Environmental Considerations There are different environmental requirements for each peripheral that can be used in your computer system. When you add peripherals, refer to the peripheral's associated data sheet to determine its environmental specifications. Flammable Materials Fundamental safeguards for computer systems should include a site well away from any sources of potential damage. The system should not be installed or operated in an environment where there is a risk of fire or explosion due to the existence of highly flammable gases, volatile liquids, 20 Chapter 2
