Description
Use this command to change the order in which slots are powered off. This command displays the current
order and then prompts you to indicate the new order.
Whenever a power supply goes out of service or a field-replaceable unit (FRU) is inserted, the system
available power is compared to the system required power to determine if there is enough power to
operate. If there is less power available than the demand, the power-off list is processed until there is
enough power for the system to operate.
If the system abruptly goes from a state in which there is enough power to run all inserted and powered
on FRUs to a state in which there is not enough power to run everything (for instance, when suddenly only
one power supply is available to power a fully loaded system), no processing of the power-off list can be
done. This is because the lack of power causes the CP boards' processors to cease execution of the
firmware. In this situation, all operation of the system terminates immediately. However, if the system is
running on two power supplies (this is not recommended) and one goes into a predicted fail state (in
which the power supply is still supplying power), the power-off list is processed as described.
The power-off list affects only the order in which slots are powered off. On power up or when an
additional power supply is added, slots are processed to verify that they can be powered up. This
processing always starts at slot 1 and proceeds to the last slot in the chassis. Also, other FRUs in the
chassis might use significant power, yet they cannot be powered off by software. For example, a missing
blower FRU might change the power computation enough to affect how many slot blades can be
powered up.
The format of the display varies, depending on the switch model and the number of slots present.
