  • Page 19: Humidity

    Each Dell system is rated to operate at altitudes from –16 to 3048 m (–50 to 10,000 ft) and can be stored at altitudes of –16 to 10,600 m (–50 to 35,000 ft).

  • Page 20: Corrosion

    Various regulatory agencies, such as the Federal Communications Commission (FCC), publish regulations to limit the amount of EMI and RFI emitted by computing equip- ment. Each Dell system is tested for compliance with these regulations. See Appendix A, “Regulatory Notices,” in this guide for information on which regulatory agencies have tested and approved your system.

  • Page 21: Magnetism

    Each Dell system, when operating, is designed to withstand a left side (for vertical ori- entation using the optional stand) and bottom half-sine pulse with a change in velocity of 50.8 centimeters per second (cm/sec) (20 inches/sec).

  • Page 22: Power Protection Devices

    Surge protectors, however, do not offer protection against brownouts, which occur when the voltage drops more than 20 percent below the normal AC line voltage level. Dell OptiPlex NX1 Net PC Systems User’s Guide...

  • Page 23: Line Conditioners

    Line conditioners keep a computer’s AC power source voltage at a fairly constant level and, therefore, can handle brownouts. Because they provide more protection than surge protectors, line conditioners cost more up to several hundred dollars. How- ever, these devices cannot protect against a complete loss of power. An uninterruptible power supply (UPS) offers the most complete protection against variations in power because it uses battery power to keep the system running when AC power is lost.
