Invisible Body Tag A Technical Specifications and Operating Limits This appendix describes the DPE technical specifications, operating limits, and shipping and storage requirements. Technical Specifications Technical specifications include power requirements, size, drive, interface, and standards information. AC Power Requirements The input current, power (VA), and dissipation per DPE 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 either: • The values for the line cord of a DPE with a single power supply. • The total values shared by the line cords of two power supplies in the same DPE, 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 DPE 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 DPE and each DAE in the cabinet.

Invisible Body Tag
This appendix describes the DPE technical specifications, operating
limits, and shipping and storage requirements.
Technical Specifications
Technical specifications include power requirements, size, drive,
interface, and standards information.
AC Power
Requirements
The input current, power (VA), and dissipation per DPE 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 either:
•
The values for the line cord of a DPE with a single power supply.
•
The total values shared by the line cords of two power supplies in
the same DPE, 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 DPE 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 DPE and each
DAE in the cabinet.
