Technical Specifications and Operating Limits A IP4700 Technical Specifications Technical specifications include power requirements, size, drive, interface, and standards information. AC Power Requirements The input current, power (VA), and dissipation per IP4700 are based on the maximum capability of the power supplies and cooling system to provide internal regulated power. Typical values will be less, depending on the number and manufacturer of disk modules. These values represent the total values shared by the line cords of two power supplies in the same IP4700, with the division between the line cords and supplies at the current sharing ratio. A failure of one of the two power supplies in the IP4700 results in the remaining supply and cord supporting the full load. You must use a rackmount cabinet with ac power distribution, and have main branch ac distribution that can handle these values for the IP4700 and each DAE in the cabinet.
