Note
Description
Powers off a component or a list of components.
For the domain shell, the specified board must be in the current domain.
All slots listed by showboards can be powered off except for system controllers (SSC0 and SSC1) and the ID board (ID0). A
You can power off any component except when the board is in the Active state (see the showboards command to display the board state). When a component is in the Active state, a warning is displayed on the console that tells you the entire domain will go down. You are asked to confirm with a warning of the consequences.
If a board is active in a domain and you forcefully power off a device (board), the keyswitch for the domain will be set to standby. To change the keyswitch setting, use the setkeyswitch command.
Repeater boards do not have an Active state. You cannot power off a Repeater board if it is being used by a domain.
You can turn off power supplies if turning off the power supply would leave sufficient power in the power grid to support the current load of the power grid. This varies with the configuration. It you attempt to power off a power supply that is required to support the current load, the power supply will not be powered off and a message stating why is displayed. You can power off redundant power supplies.
If powering off a fan would result in insufficient cooling, it cannot be powered off.
