DAE2P/DAE3P Hardware Reference
A-2
Technical enclosure specifications include power requirements, size,
drive, interface, and standards information.
The input current, power (VA), and dissipation per DAE2P/DAE3P
are based on the requirements that a maximum enclosure
configuration places on 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 a single power supply line cord, or
the sum of values shared by the line cords of two power supplies
in the same DAE2P/DAE3P, with the division between the line
cords and supplies at the current sharing ratio (approximately
50% each).
A failure of one of the two power supplies in the enclosure 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 each disk
enclosure in the cabinet.
