Table 5-7 shows similar information for full-wide compute nodes of 1000 W, 1200
W, and 1400 W with a throttling policy enabled. The number of supplies indicated
in the table is theoretical, and might not represent a practical configuration. For
example, although a specific number of supplies may be adequate to power the
indicated configuration under normal operation, it may require the compute
nodes to throttle the power to unrealistic or impossible levels during a fault to
keep the system running.

a. Theoretical number. Might require unrealistic throttle levels.
b. If there is a power fault, all compute nodes in the chassis must throttle the power to the average
power indicated in the Fault column.
