1.4 Electrical Power Requirements
Oracle Exadata Racks can operate effectively over a wide range of voltages and
frequencies. However, they must have a reliable power source. Damage may occur if
the ranges are exceeded. Electrical disturbances such as the following may damage
Oracle Exadata Rack:
•
Fluctuations caused by brownouts
•
Wide and rapid variations in input voltage levels or in input power frequency
•
Electrical storms
•
Faults in the distribution system, such as defective wiring
To protect Oracle Exadata Rack from such disturbances, you should have a dedicated
power distribution system, power-conditioning equipment, as well as lightning arresters
or power cables to protect from electrical storms.
1.4.1 PDU Power Requirements
Each rack has two pre-installed power distribution units (PDUs). The PDUs accept
different power sources. You must specify the type of PDU that is correct for your
Oracle Exadata Rack and data center.
