Site Requirements
For proper DPE operation, the installation site must conform to
certain environmental specifications. These are detailed below and in
Appendix A.
Power To determine a DPE’s power requirements, use the power rating on
the enclosure label. This rating is the maximum power required for a
fully loaded enclosure. The input current, power (VA), and
dissipation for the DPE are based on the maximum capability of the
power supplies and cooling system to provide internally regulated
power. Typical values will be less, depending on the number and
manufacturer of disk drives. These values represent either the values
for the power cord of a DPE with a single power supply, or the total
values shared by the line cords of two power supplies in the same
DPE, with the division between the power cords and supplies at the
current sharing ratio. If one of the two power supplies fails, the
