  • Page 13: Caution: Safety Instructions

    Caution: Safety Instructions Use the following safety guidelines to ensure your own personal safety and to help protect your system from potential damage. General • Observe and follow service markings. Do not service any product except as explained in your system documentation. Opening or removing covers that are marked with the triangular symbol with a lightning bolt may expose you to electrical shock.
  • Page 14 Caution: Safety Instructions • Use only approved power cable(s). If you have not been provided with a power cable for your system or for any AC-powered option intended for your system, purchase a power cable that is approved for use in your country. The power cable must be rated for the product and for the voltage and current marked on the product's electrical ratings label.

  • Page 15: Rack Mounting Of Systems

    NOTE: Your system is safety-certified as a free-standing unit and as a component for use in a Dell rack cabinet using the customer rack kit. The installation of your system and rack kit in any other rack cabinet has not been approved by any safety agencies. It is your responsibility to have the final combination of system and rack kit in a rack cabinet evaluated for suitability by a certified safety agency.

  • Page 16: Modems, Telecommunications, Or Local Area Network Options

    Caution: Safety Instructions • After a component is inserted into the rack, carefully extend the rail into a locking position, and then slide the component into the rack. • Do not overload the AC supply branch circuit that provides power to the rack. The total rack load should not exceed 80 percent of the branch circuit rating.

  • Page 17: Protecting Against Electrostatic Discharge

    Caution: Safety Instructions When Working Inside Your System Protecting Against Electrostatic Discharge Static electricity can harm delicate components inside your system. To prevent static damage, discharge static electricity from your body before you touch any of the electronic components, such as the microprocessor. You can do so by periodically touching an unpainted metal surface on the chassis.
