2.2Electrical Specifications

SPARC Enterprise M8000/M9000 Servers can use two types of power supply: single- phase power and three-phase power. Redundant power cables are supported only on servers that have the dual power feed option. The dual power feed option is included by default on servers that are configured for three-phase power.

Note – Power cables are not redundant on single power feed servers without the dual power feed option. On servers that have single power feed, all power cables must be connected and powered on at all times.
