The IBM NeXtScale n1200 Enclosure includes 10 hot swappable fans and six hot
swappable power supplies. These are installed in the rear of the chassis, as
shown in Figure 1-2.

Six single-phase power supplies were chosen to enable power feeds from one or
two sources of three-phase power.
Also, in the rear of the chassis is the Fan and Power Controller, which controls
power and cooling aspects of the chassis.
1.2.2 IBM NeXtScale nx360 M4 compute node
The first server that is available for NeXtScale System is the nx360 M4 compute
node. It fits in a half-width bay in the n1200 Enclosure, as shown in Figure 1-3 on
page 5. On the front is the power button, status LEDs, and connectors. There is a
full-height, half-length PCI Express card slot, and a PCI Express mezzanine card
slot that uses the same mezzanine card type as our rack mount servers.
