2-Gigabit Disk-Array Enclosure (DAE2) Hardware Reference
A-2
Technical enclosure specifications include power requirements, size,
drive, interface, and standards information.
The input current, power (VA), and dissipation per DAE2 are based
on the requirements that a maximum DAE2 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 DAE2, 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 DAE2 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.
