The server uses AC power. The values in the following table are the power supply specifications.
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. For up-to-date information about the power consumption, go to Oracle's Sun Power Calculators web site and click the Sun Server X4-2L link: http://www.oracle.com/us/products/servers-storage/sun-power-calculators/index.html
Table 5 Power Supply Specifications
The Sun Server X4-2L can operate effectively over a range of voltages and frequencies. However, it must have a reliable power source. Damage to the server 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
Faults in the distribution system, such as defective wiring
To protect your server 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.
The following sections discuss specific power requirements.
