Rear Components - IBM NeXtScale System Planning And Implementation Manual

3.1.2 Rear components

The n1200 provides shared high-efficiency power supplies and fan modules. As
with IBM BladeCenter and IBM Flex System, the NeXtScale System compute
nodes connect to a midplane, but this connection is for power and control only;
the midplane does not provide any I/O connectivity.
Figure 3-4 shows the major components that are accessible from the rear of the
chassis.

At the rear of the chassis, the following types of components are accessible:
Power supplies
The IBM NeXtScale n1200 Enclosure has a six-power supply design, all in
one power domain. This configuration allows clients with 100 V - 240 V utility
power (in single or three-phase) to power up the chassis by using the
infrastructure they already have. For three-phase power, the phases are split
in the PDU for single phase input to the chassis power supplies.
For more information about the power supplies, see 3.4, "Power supplies" on
page 38.
