Power Supply Specifications

The servers contain hot-swappable, redundant power supplies. The SPARC M8-8 and SPARC M7-8 servers contain 6 power supplies, and the SPARC M7-16 server has 16 power supplies. These specifications are for each power supply and not for the entire server.

Note -  All power supplies must be installed, and all power cords must be connected, to power the server.

Use these power supply specifications only as a planning aid. For more precise power values, use the online power calculator to determine the power consumption of the server with your configuration. To locate the appropriate power calculator, go to the following web site and navigate to the specific server page:
