Grounding for Single-phase Power Supply

SPARC Enterprise M8000/M9000 servers used with a single-phase power supply ships with a grounded (three-wire) power cable.

The power cable must always be connected to a power outlet that has a grounding receptacle.

Grounding for Three-phase Power Supply

The power cable is not supplied with three-phase power supply SPARC Enterprise M8000/M9000 servers.

Since different grounding methods are used depending on the building where the system is installed, check the grounding type and refer to related documents (e.g., IEC documents) in order to use the correct grounding method. Make sure that the facility administrator or a qualified electrical engineer verifies the grounding method for the building and performs the grounding work.
