The power monitor compares the available power with the power required to determine if there will
be enough power to operate. If it is predicted to be less power available than required, the
power-off list is processed until there is enough power for operation. By default, the processing
begins with slot 1 and proceeds to the last slot in the chassis. As power becomes available, slots
are powered up in the reverse order. During the initial power up of a chassis, or using the
slotPowerOn command, or the insertion of a blade, the available power is compared to required
power before power is applied to the blade.
Some FRUs in the chassis may use significant power, yet cannot be powered off through software.
The powerOffListShow command displays the power off order.
In the Backbones, the core blades and CP blades cannot be powered off from the CLI. You must
manually power off the blades by lowering the slider or removing power from the chassis. If there is
no CP up and running, then physical removal or powering off the chassis is required.
