Electrical Precautions; Battery Precautions - Hitachi NAS Platform 4000 Series Hardware Reference Manual

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 off 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 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.

Battery precautions

To ensure your safety and the safe handling of batteries, follow these handling
guidelines.
