follow all of the safety precautions and instructions.
Caution: Observe safe lifting practices. Each server or each storage array can
weigh 57 lb. (26 kg) or more. At least two people are required to handle and
position a server in a rack.
Caution: There is a risk that a cabinet could fall over suddenly. To prevent this
from occurring:
■If your system comes with a rack stabilizer plate, install it.
■Fill all expansion cabinets, including all storage enclosures, from the
bottom to the top.
■Do not remove more than one unit from the rack at a time.
Chapter 2: Safety information

To help prevent serious injuries, load the components in the storage cabinet in the
prescribed order:
1. If present, install the rack stabilizer plate to the front of the system cabinet.
2. Load the Fibre Channel (FC) switches in the storage cabinet at the positions
recommended in the System Installation Guide. The positions can be adjusted
according to a specic storage cabinet conguration.
3. Load and position the server(s) directly above the FC switches, if used in your
conguration.
4. The System Management Unit (SMU), if used in your conguration, should be
placed directly below the FC switches.
5. The rst storage enclosure should be positioned at the bottom of the storage
cabinet. Additional enclosures are then placed above existing enclosures, going
towards the top of the system cabinet.
6. Once the bottom half of the storage cabinet has been lled, the top half of the
storage cabinet can be lled. Begin by placing a storage component directly above
the server and then ll upwards.

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.
Caution: Turn o all power supplies or remove all power cords before
undertaking servicing of the system.
■Unplug a system component if it needs to be moved or if it is damaged.
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 dierent 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.
Battery precautions
To ensure your safety and the safe handling of batteries, follow these handling
guidelines.
Electrical precautions
Chapter 2: Safety information
Hitachi NAS Platform and Hitachi Unied Storage Series 4000 Hardware Reference 19

Caution: Ensure that batteries are replaced in accordance with the
instructions in the manual or their relevant manual.
■Only replace a battery with one of the prescribed type. Use of the wrong battery type
or incorrect replacement may result in an explosion.
■Dispose of batteries according to the laws and regulations of your region.
■French:
●Seulement remplacer une batterie avec le type recommandé. L'utilisation du
mauvais type de batterie ou une mauvaise installation peut entraîner une
explosion.
●Jetez les batteries conformément aux lois et règlements de votre région.

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 elds.
■All supplied plug-in modules and blanking plates must be in place to complete the
internal circuitry and enable air to ow correctly around an enclosure.
■Using the system for more than a few minutes with modules or blanking plates
missing can cause an enclosure to overheat, leading to power failure and data loss.
Such use may invalidate the warranty.
■A loss of data can occur if a hard drive module is removed. Immediately replace any
modules that are removed. If a module is faulty, replace it with one of the same type,
of at least the same capacity and speed.
■Always shut down the system before it is moved, switched o, or reset.
