2 powerOffListShow powerOffListShow Displays slot power-off list order. Synopsis powerofflistshow Description Use this command to display the order in which the physical slots will be powered off. The system-available power is compared to the system demand power to determine if there is enough power to operate. If there is less power available than the demand, then the power-off list is processed until there is enough power for the system to operate. Note that if the system abruptly goes from a state with enough power to run all inserted and powered FRUs to a state with too little power to run everything, no processing of the power off list can be done. This is due to the lack of power causes the CP boards' processors to cease executing the firmware. In this situation, all operation of the system terminates immediately. An example of this situation is when a third power supply is removed from the chassis, so that suddenly only one power supply is available to power a fully loaded system. However, if the system is running on two power supplies (this is not recommended) and one goes into predicted fail state (in which the power supply is still supplying power), the power off list processes as described. The execution of this command is subject to Admin Domain restrictions that may be in place. Operands none Examples To display the slot power off list order: switch:admin> powerofflistshow Slot 10 will be powered off 1st Slot 9 will be powered off 2nd Slot 8 will be powered off 3rd Slot 7 will be powered off 4th Slot 6 will be powered off 5th Slot 5 will be powered off 6th Slot 4 will be powered off 7th Slot 3 will be powered off 8th Slot 2 will be powered off 9th Slot 1 will be powered off 10th See Also chassisShow, powerOffListSet, psShow, slotPowerOff, slotPowerOn, slotShow 548 Fabric OS Command Reference Manual 53-1000436-01

powerOffListShow
Displays slot power-off list order.
Synopsis
powerofflistshow
Description
Use this command to display the order in which the physical slots will be powered off. The
system-available power is compared to the system demand power to determine if there is enough
power to operate. If there is less power available than the demand, then the power-off list is
processed until there is enough power for the system to operate.
Note that if the system abruptly goes from a state with enough power to run all inserted and
powered FRUs to a state with too little power to run everything, no processing of the power off list
can be done. This is due to the lack of power causes the CP boards’ processors to cease executing
the firmware. In this situation, all operation of the system terminates immediately. An example of
this situation is when a third power supply is removed from the chassis, so that suddenly only one
power supply is available to power a fully loaded system. However, if the system is running on two
power supplies (this is not recommended) and one goes into predicted fail state (in which the
power supply is still supplying power), the power off list processes as described.
The execution of this command is subject to Admin Domain restrictions that may be in place.
