ac distribution units inside a rack cabinet or directly into external
receptacles. Similarly, the right and left power supplies of the DS4000
storage expansion enclosures attached to the DS4300 storage
subsystem should be plugged into the same two independent external
power circuits as the DS4300 storage subsystem. See Figure 72 for an
example of redundant power cabling.
Exception: The DS4300 single-controller storage subsystem (Model
6LU/6LX) has only one power supply, so it does not support power
redundancy.

5. Go to "Turning the storage subsystem on and off" on page 92 for the initial

startup of the storage subsystem.

Install the storage-management software by using the procedures in the IBM
DS4000 Storage Manager Installation and Support Guide for your operating system.
Use that document and the online help to configure the logical drives, partitions,
and so on for the RAID controllers. Use your operating system documentation to
make the new logical drives accessible to the operating system.
