For details about power requirements, see “Electrical requirements” on
page 25.

Attention: Before you power on the DS4800 Storage Subsystem, the
DS4800 must be cabled to at least one storage expansion enclosure populated
with at least two drives. If at least two drives are not installed in each attached
storage expansion enclosure when you power on the DS4800, your standard
storage partition key will be lost and will need to be regenerated using
instructions on the IBM DS4000 Solutions and Premium Features Web site:
https://www-912.ibm.com/PremiumFeatures/
Additionally, if at least two drives are not installed in each attached storage
expansion enclosure, the resulting insufficient load to the storage expansion
enclosure power supply CRUs might cause the drive expansion enclosure
power supply CRUs to intermittently appear as failed and then reappear in an
optimal state, falsely indicating that the power supply CRUs are bad.
