Electrical precautions
To help ensure your safety and the safe handling of equipment, follow these
guidelines.
• Provide a suitable power source with electrical overload protection to meet
the power requirements of the entire system (the server/cluster, and all
storage subsystems and switches). The power requirements per cord are -
North America: 2 phase, 208Vac, 24A max; 1 phase 110Vac, 16A max.
Europe: 230Vac, 16A max.
• Provide a power cord that is suitable for the country of installation (if a
power cord is not supplied).
• Power cords supplied with this server or system may be less than 1.5m in
length. These cords are for use with a power distribution unit (PDU) which
is mounted inside the 19 inch rack. If you require longer cables, please
contact your local sales representative.
• Provide a safe electrical ground connection to the power cord. Check the
grounding of an enclosure before applying power.
• Only operate the equipment from nominal mains input voltages in the
range 100 - 240Vac, 6A max, 50/60Hz.
• Unplug a system component if it needs to be moved or if it is damaged.
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)
modules. These units are fragile. Handle them with care and keep them
away from strong magnetic fields.
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.
