The following configuration options are available:
Enabled
You can specify the maximum amount of power that the server can consume at one time. This maximum
can be any amount between 0 watts and 1100 watts.
Disabled
No power usage limitations are imposed upon the server. The server can use as much power as it
requires.
If the server encounters a spike in power usage that meets or exceeds the maximum configured for the server,
Cisco UCS Manager does not disconnect or shut down the server. Instead, Cisco UCS Manager reduces the
power that is made available to the server. This reduction can slow down the server, including a reduction in
CPU speed.
