Viewing and Modifying PCIe Power Allocation
The PCIe Power Allocation allows you to view and change the maximum
power allocated to the PCIe expansion cards. The power allocated should be
between 100W and 500W. Allocating too much power may result in the
blade not powering on or may prevent other blades in the chassis from
powering on. If the PCIe expansion card consumes more power than the
allocation, the blade will power off. When modifying the PCIe power
allocation, the new power allocation value is used when the system boots.
NOTE: The PCIe Power Allocation information does not apply to all platforms and
will not display for platforms where it does not apply.
NOTE: You must have Administrator privileges (Configure iDRAC and Execute
Server Control Commands) to edit the PCIe Power Allocation value.
