• Policy-driven chassis-level power capping
• Manual blade-level power capping

Power Management Precautions
Ifthe CIMC is reset,the power monitoring functions of Cisco UCS become briefly unavailable for as long
asit takes for the CIMC to reboot. While this usually only takes 20 seconds, there is a possibility that the peak
powercap could be exceeded during that time. To avoid exceeding the configured power cap in a very low
power-cappedenvironment, consider staggering the rebooting or activation of CIMCs.
