Grounding for Three-phase Power Supply
The power cable is not supplied with the three-phase power supply M8000/M9000 servers.
Ensure that the power cable wiring includes a ground wire from the distribution board to the
terminal board of the power cabinet, as a part of the on-site electrical work.
For the installation positions, see
This server allows the use of grounding wire with another grounding wire for shared
grounding; however, the grounding methods may vary by the building where the system is
installed.
Check the related standards in order to use the correct grounding method.
The grounding resistance must not be greater than 10 Ω. The grounding method varies by the
building where you install the server. Make sure that the facility administrator or a qualified
electrical engineer verifies the grounding method for the building and performs the
grounding work.

Checking the Installation Location

For the high-end servers installation, secure a service area (maintenance area) that is large
enough for each system (cabinet).
For details, see the SPARC Enterprise M8000/M9000 Servers Site Planning Guide.

Rack Space for the M8000 Server

A 12-pitch sized rack space (12U) is provided in the upper part of the cabinet of the M8000
server.
In this rack space for a M8000 server, the rack-mountable dual-power feed uses 6U of rack
space, and the rest of the space can be used for the customer external devices.
