Symptoms

Certain Dell computers (such as Dell PowerEdge servers) are designed to work in accordance with electric specifications defined by the IEEE organization. The following information may be used to determine if the site power is within the IEEE standard for use with computing equipment:

Minimal site power requirements according to the IEEE Std 518-1982:

  • Frequency within +/- 0.5Hz. (This varies from country or region to country or region. See Table 1, below, for the country-specific information.)
  • Steady-state voltage within +/-8% of normal-rated voltage. (This varies from country or region to country or region. Refer to Table 1, below, for the country-specific information.)
  • Transient voltage conditions not exceeding +15% or -18% nominal, and returning to normal voltage within 0.5 seconds.
  • Total harmonic voltage distortion not exceeding 5%.
In order to verify the quality of the site power, a licensed electrician with equipment that can detect the above conditions are required.
 
NOTE: An example of such equipment would be a Dranetz Power Platform 4300 line analyzer.
