Thefollowing configuration options areavailable:
Enabled
Youcan specify the maximum amount of power that the server can consume at one time. This maximum
canbe any amount between 0 watts and 1100 watts.
Disabled
Nopower usage limitations are imposed upon the server. The server can use as much power as it
requires.
Ifthe server encounters a spike in power usage that meets or exceeds the maximum configured for the server,
CiscoUCS Manager does notdisconnect or shutdown theserver. Instead, Cisco UCS Manager reduces the
powerthat is made availableto the server. This reduction can slow down the server, including a reduction in
CPUspeed.
