Data protection precautions

To help ensure the protection of data and safe handling of equipment, follow
these guidelines.
• Each storage enclosure contains multiple removable hard disk drive (HDD)

Caution: Turn off all power supplies or remove all power cords before
undertaking servicing of the system.
Note: For additional data protection, Hitachi recommends that you use an
external UPS to power the server. Also, each of the redundant power
supplies in the server and in the storage subsystems should be operated
from a different mains power circuit in order to provide a degree of
protection from mains power supply failures. In the event that one circuit
fails, the other continues to power the server and the storage subsystem.
