2.4.3 Grounding
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.
