Electrical Power Requirements

Language:

The Oracle ZFS Storage ZS5-ES controller uses AC power. The following table lists the power supply specifications for the controller.

Note - The power dissipation numbers listed in the following table are the maximum rated power numbers for the power supply used in the system. The numbers are not a rating of the actual power consumption of the system.

Table 5 Power Supply Specifications

Parameter	Specification
Voltage (nominal)	100 to 127 VAC; 200 to 240 VAC
Input current (maximum)	7.2 A @ 100-127 VAC; 3.4 A @ 200-240 VAC
Frequency (nominal)	50/60 Hz (47 to 63 Hz range)

The controller can operate effectively over a range of voltages and frequencies. However, it must have a reliable power source. Damage to the controller might occur if the ranges are exceeded. Electrical disturbances such as the following might damage the system:

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 your controller 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.

See the following sections for additional power specifications.
