IMPORTANT
Systems with DC power are intended for use in environments with redundant and
highly available power sources (for example, "Central Office" grade power within the
telecommunications industry), and DC power provided by the site must meet this
requirement. The sudden loss of all incoming DC power to a storage system may
cause unexpected abnormal behavior of the storage system and loss of write-cache
data.
Power distribution must support the number of outlets required for the device (two
per enclosure) and the device power rating.
