Electrical Power

Oracle Cloud at Customer can operate effectively over a wide range of voltages and frequencies. However, it must have a reliable power source.

Damage may occur if the ranges are exceeded. Electrical disturbances such as the following may damage an Oracle Cloud at Customer:

• 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 the system, dedicated power distribution system and power-conditioning equipment should be used. Lightning arresters or power cables should be used to protect from electrical storms.

Each rack has two pre-installed Power Distribution Units (PDUs). The PDUs accept different power sources. You must select the type of PDU that meets the requirements for your data center.

Note:

PDUs have either two or three power cables (whips) each, therefore four or six power cables require connecting per rack. All power cables of the rack must be connected to the electrical outlets of the data center.

See Power Distribution Units Specification for more information about low and high voltage PDUs and the regions where they can be used.
